Theta Projection Creep Life Model| Using Abaqus User-Subroutines for Creep Modelling of Gas Turbine Blades

 250.0
Creep is one of the most significant failure modes in gas turbine components where the working temperature and stresses are high for a prolonged period of time. Existing creep models in commercial analysis software like Abaqus are not adequate to model all stages of creep namely – primary, secondary, and tertiary stages. Theta projection method is a convenient method proven to predict all stages of creep, especially the tertiary stage where strain rates are high leading to internal damage and fracture. The aim of the project is to develop a user subroutine for Abaqus to model creep in gas turbine components using the Theta projection method. The constitutive model for the Theta projection method based on the accumulation of internal state variables such as hardening, recovery, and damage developed by (R.W.Evans, 1984) is adopted to compile a Fortran code for the user subroutine. The user subroutine is validated through several test cases and comparing the results with experimental creep data. Creep analysis of a sample gas turbine blade is then performed in Abaqus through the user subroutine and the results are interpreted. Results of test cases validate the accuracy of the Theta Projection Method in predicting all primary, secondary, and tertiary stages of creep than existing creep models in Abaqus. Results at interpolated & extrapolated stress & temperature conditions with robust weighted least square regression material constants show the convenience in creep modeling with less input data than existing models. Results of creep analysis in a sample gas turbine blade not only predicted the creep life but also indicated the internal damage accumulation. Thus, creep modeling of gas turbine components through the user subroutine at different load conditions could lead us to more reliable creep life predictions and also indicate the regions of high creep strain for improvements in the early stages of design.

Simulation of pitting corrosion with scripting in Abaqus

 230.0
(3)
Pitting corrosion is a form of extremely localized corrosion that leads to the random creation of small holes in metal. It can occur with random sizes and distributions, typically modeled as conical or cylindrical shapes. This type of corrosion reduces the strength of structures and increases stress concentration. So, it can lead to various destructive effects such as pipes bursting and reduced resistance to internal pressure. By pitting corrosion simulation, you can assess how corrosion affects stress, vibration, heat transfer, and other factors. This is crucial for enhancing the durability and safety of structures such as storage tanks, shafts, tubes, pipes, and other industrial components. This tutorial includes two scripts for pitting corrosion analysis. They help you to conduct Abaqus pitting corrosion simulation for different examples including a simple plate and a shaft.

Continuously Reinforced Concrete Pavement (CRCP) Cracking Analysis

 210.0
(1)

The increasing adoption of continuously reinforced concrete pavement (CRCP) in highway pavement design is driven by its demonstrated superior performance. Critical to evaluating the long-term effectiveness of CRCP is the understanding of early-age cracks (CRCP crack analysis), which has garnered significant interest from highway departments. This Abaqus Continuously reinforced concrete pavement modeling project aims to establish precise design parameters for CRCP and analyze the formation of crack patterns. By accounting for stress factors such as environmental conditions and CRCP shrinkage modeling, the project offers valuable insights into predicting the likelihood of crack initiation and propagation within the concrete slab. These insights are instrumental in enhancing the durability and performance of CRCP structures, thus advancing the efficiency and effectiveness of highway infrastructure.

Optimization in ABAQUS

 300.0
Notice: 2 hours of the package is available now; during 1-month after purchase, it will be completed.  Optimization is a process of finding the best solution to a problem within a set of constraints. It involves maximizing or minimizing an objective function while satisfying a set of constraints. Optimization in Abaqus involves the use of advanced algorithms and techniques to improve the design of structures and systems. Abaqus provides a range of optimization tools, including topology optimization, size optimization, and shape optimization. These tools help in improving the performance of structures by reducing their weight, increasing their stiffness, and minimizing their stress levels. In this package, all types of optimization, such as Topology, will be discussed; after each lesson, there will be workshops to help you to understand optimization with practical examples.

Script to transfer load from CFD to structural model in Abaqus

 160.0
(1)
FEA offers various loading types, such as force, pressure, and temperature, which can be applied to different parts of an object, such as points, surfaces, edges, nodes, and elements. Therefore, applying accurate loading conditions on these features is necessary for reliable simulation results and the safe design of structures. Sometimes, the loading conditions are obtained by another analysis, such as CFD, and need to be transferred and applied to the structural model for the structural analysis; during this transfer, the loads might not be appropriately applied to the model, especially when the loads are complicated like the pressure profile of a space rocket. So in this package, a Python script is presented to solve this issue and transfer the loads properly to the structural model.

3D printing is a technique for creating three-dimensional objects by layering materials such as plastic or metal based on a digital design. 3D printing simulation involves the use of software to predict and enhance the printing process, resulting in more efficient and precise production. This training package is based on the use of subroutines and Python scripting. Following an introduction to the 3D printing process, this method with all its details is explained. Two workshops are then conducted for this method. The first workshop covers 3D printing simulation of a gear with a uniform cross-section, while the second workshop covers a shaft with a non-uniform cross-section.

3D printing is a process of creating three-dimensional objects by layering materials, such as plastic or metal, based on a digital design. 3D printing simulation involves using software to predict and optimize the printing process, allowing for more efficient and accurate production. This educational package includes two 3D printing modeling methods. The first method is based on the use of subroutines and Python scripting. After an introduction to the 3D printing process, the first method with all of its detail is explained; then, there would be two workshops for this method; the first workshop is for the 3D printing simulation of a gear with uniform cross-section and the second one is for a shaft with non-uniform cross-section. The second method uses a plug-in called AM Modeler. With this plug-in, the type of 3D printing can be selected, and after inserting the required inputs and applying some settings, the 3D printing simulation is done without any need for coding. Two main workshops will be taught to learn how to use this plug-in: "Sequential thermomechanical analysis of simple cube one-direction with LPBF 3D printing method using the trajectory-based method with AM plug-in" and "3D printing simulation with Fusion deposition modeling and Laser direct energy deposition method with AM plug-in".
