Implementation of Soil Constitutive Models in Abaqus | With a Special Focus on CSJ Models
Constitutive model implemented in calculation code, play an important role in the material behaviors prediction. In the field of geotechnical engineering there are numerous soil constitutive models. By installing these models in a finite element code such as Abaqus, their development, efficiency and advancement can be increased. Also, more and more complex engineering problems can be solved by this method. But to do this, you need a proper understanding of the mathematical and programming basics of these models. This tutorial focuses on implementing advanced constitutive models in Abaqus, particularly for simulating soil behavior. Focusing on the CJS model, this tutorial tries to teach how to work and how to program these models in Abaqus code. It includes detailed explanations of VUMAT and UMAT subroutines and practical examples of implementing the CJS model.

Tunnel excavation simulation using TBM in Abaqus
Notice: This package will be available one week after purchase.
Tunnel Boring Machines (TBMs) are advanced construction equipment used to excavate tunnels with efficiency and precision. These massive machines consist of a rotating cutting wheel equipped with disc cutters, which excavate the soil or rock, and a conveyor system that removes the excavated material from the tunnel. TBMs play a crucial role in various industries, including transportation, mining, and underground infrastructure development. TBM simulation is of utmost importance in the planning and execution of tunneling projects. It allows engineers and project managers to evaluate the feasibility of different tunneling methods, optimize the design and operation of TBMs, and predict potential challenges and risks. By simulating the TBM's performance and behavior under various geological conditions, factors such as ground stability, excavation rates, cutter wear, and potential impacts on surrounding structures can be analyzed and mitigated. In this package, you will learn how to do a TBM simulations by several practical examples.
A tunnel is an underground or underwater passage for transportation, utility lines, or water pipelines. Tunnels are critical infrastructure, and their safety and reliability are essential for ensuring public safety and the smooth functioning of society. Tunnel simulation involves using computer models to predict the behaviour of tunnels under different types of loading conditions, such as earthquakes, floods, or explosions. These simulations can help engineers and policymakers assess the safety and reliability of tunnels, identify potential failure modes, and develop strategies to mitigate risks. By using advanced simulation techniques, engineers can better understand the complex behavior of tunnels and design more effective and durable structures. Tunnel simulation is an essential tool for ensuring the safety and resilience of tunnels and the infrastructure they support. Some workshops are presented in this package to teach you how to simulate and analyze tunnels in Abaqus; two of these workshops are Damage analysis of an underground box tunnel subjected to surface explosion and Tunnel dynamic analysis subjected to internal blast loading using CEL method.
Eulerian Abaqus and CEL modeling
The Eulerian method is a numerical technique used to analyze fluid mechanics problems. In this approach, the fluid is treated as a fixed grid, where the nodes remain stationary while the fluid flows through them. The Eulerian Abaqus method can be used to analyze fluid-structure interactions, such as fluid impact on structures or the behavior of fluids in containers. To use the Eulerian method in Abaqus, the desired geometry must first be meshed using Eulerian elements. The material behavior of the fluid is then defined using appropriate equations of state. Finally, the boundary conditions and loading are applied, and the system is solved using the appropriate numerical method, such as the finite element method. This package will teach you how to use this method and various practical examples. Also, this package covers several practical examples in Abaqus CEL method.
A dam is a large concrete or earthen barrier built across a river or other waterway to create a reservoir for storing water. Dams are critical infrastructure for providing water for irrigation, drinking, and hydroelectric power generation. However, they are also susceptible to damage from natural disasters and human-made threats, such as earthquakes, landslides, and terrorist attacks. Abaqus can predict the behavior of dams under different loading conditions, including earthquakes, floods, and explosions. It also can model the interaction between the dam, water, and soil, making it a comprehensive and powerful tool for dam engineering. In this package, you will learn how to model dams in different conditions, such as dam simulation subjected to earthquakes in interaction with water and soil and dam simulation subjected to an underwater explosion.
An explosion is a rapid and violent release of energy, usually accompanied by a loud noise, heat, and pressure waves. Explosions can be caused by a variety of factors such as chemical reactions, combustion, nuclear reactions, or mechanical failure. Explosions can cause severe damage to buildings, infrastructure, and human life. To minimize the impact of such incidents, accurate and reliable simulation of explosions is crucial. Explosion simulation involves modeling the complex interactions of blast waves, shock waves, and debris with the surrounding environment. By simulating explosions, engineers and scientists can identify potential risks and develop effective safety measures. In this package, you will learn how to model explosions in different situations with practical examples, such as Air blast explosion simulation inside an RC room and Subsurface explosion simulation on buried steel pipelines.
Geostatic Relates to the pressure exerted by the earth or similar substance. Total stress at a point due to the combined weight of the soil or rock (solids plus water) and the load on the foundation is called Geostatic stress. Geostatic analysis is used in cases such as earthquakes, designing a dam, analyzing the foundation of a structure, etc. In this package, three workshops are presented to learn the Geostatic analysis: The first workshop analyzes a water column broke under the weight of gravity, the second workshop simulates an earthquake load over a gravity dam in contact with water and dirt, the last workshop models cylindrical tank's water sloshing phenomenon.
A mathematical model called the Mohr-Coulomb theory describes how brittle materials, such as concrete or rubble piles, react to both shear stress and normal stress. This rule is followed by the majority of traditional engineered materials in at least some of their shear failure envelope. In this package, you will learn how to use this theory in four practical examples: Analysis of surface explosion damage to an underground box tube in ABAQUS, dynamic analysis of a tunnel in soil subjected to internal blast loading, An internal explosion-related numerical simulation of the behavior of a pipeline's damage mechanics, and for cases utilizing crashworthiness, simulate an Eulerian method to soil impact analysis.
Earthquake simulation in Abaqus
It is known that an earthquake is a disastrous event that can cause great damage to buildings, structures, and even people. So it's essential to know how a structure will behave when subjected to an earthquake. Therefore engineers must take into account the possibility of an earthquake when designing a structure. With finite element analyses, engineers can predict the behaviour of structures under earthquake loading. With this method, they can determine the best way to design a structure to withstand an earthquake. In this package, you can learn how to do earthquake simulation in Abaqus to have the best design for your structure to save human lives. Three practical examples are presented to you to start simulating earthquakes: “simulating an earthquake over a gravity dam in contact with water and soil”, “simulating an earthquake load over a water-filled tank”, “Abaqus-Micro model simulation of seismic load over masonry wall (concrete brick)”.
If you need common industrial simulations in the fields of forming, fracture, explosion, impact, etc., this package can provide you with comprehensive training along with an instructional video file and software file. You can quickly meet your educational needs in learning the elementary and intermediate level of Abaqus software using this package.
