In the present Abaqus tutorial for civil engineering package, we have presented all the software skills that a civil engineer needs when he wants to use his/her engineering knowledge in computer-aided designing. Abaqus tutorial for civil engineering covers all you need to simulate concrete, reinforcements, buckling, frequency, damage, composite, cohesive and more topics. You can download the syllabus of this package here.  

3D continuum Abaqus HASHIN progressive Damage for composite materials (VUMAT Subroutine)

 320
This tutorial teaches how to simulate damage in 3d continuum composite materials in ABAQUS. As you know, Abaqus does not have any material model for 3d composite materials. So, the user needs to write a customized subroutine to simulate damage initiation and progressive damage for composite materials in ABAQUS. In this package, one of the most practical damage initiation criteria (Hashin) is used to detect failure. It should be mentioned that this subroutine includes gradual progressive damage based on the energy method. This complex subroutine could be used for static and dynamic problems.

DFLUX Subroutine (VDFLUX Subroutine) in ABAQUS

 140
DFLUX subroutine (VDFLUX Subroutine) is used for thermal loading in various body flux and surface flux states in heat transfer and temperature displacement solvers when flux load is a function of time, place, or other parameters. In this package, you will learn “when do you need to use this subroutine?”, “how to use the DFLUX subroutine”, “what is the difference between DFLUX & VDFLUX?”, “how to convert DFLUX to VDFLUX and vice versa?”, and “How to use it in an example?”. Three workshops are presented so you can learn all these stuff in action: Simulation of welding between two plate with DFLUX subroutine, Simulation of Arc welding between two tube with DFLUX, and Simulation of different types of functional heat flux(Body-surface-Element) in plate with Johnson-cook plasticity with VDFLUX subroutine(Thermomechanical Analysis).

Advanced UMAT Subroutine (VUMAT Subroutine) – Abaqus UMAT tutorial

 290
This training package helps Abaqus users to prepare complex UMAT and VUMAT subroutines. This Abaqus UMAT tutorial package is suitable for those who are familiar with subroutine or want to learn UMAT/VUMAT subroutine Professionally. Equations for computational plasticity based on kinematic stiffness are also discussed. In addition, metal damage has been implemented based on Johnson Cook's model. Watch Demo

Simulation of Unidirectional Composite Damage in ABAQUS

 130

This package introduces and applies various theories to initiate and progress damage in composite materials based on ABAQUS capabilities for different elements. As you know, according to the modeling done by the micro or macro method, the way of defining the Abaqus composite damage completely follows the separate method in ABAQUS. This training package is customized for macro modeling of composite structures.

Additive manufacturing simulation with Abaqus AM modeler plugin

 340
Since computer-aided design and 3D printing directly result in the fabrication of actual components, 3D printing technology is crucial. The ADM plug-in is used as part of this teaching package to model additive manufacturing. This plugin is a cutting-edge tool for simulating 3D printing and covering many ADM procedures. It appears to be the best simulator for additive manufacturing or 3D printing available right now!

Additive manufacturing simulation with Abaqus subroutine & python | 3D printing Python

 350
The process of building a three-dimensional object from a CAD model or digital 3D model is known as additive manufacturing or 3D printing. In an additive process, an object is made by adding layers of material one after another until the product is made. This package will teach you additive manufacturing or 3d printing simulation based on the use of subroutines and Python scripting and was done by a team with the goal of coding all the steps of 3D printing.

Composite Fatigue Simulation with UMAT Subroutine in ABAQUS (unidirectional)

 420
The composite fatigue training package completely teaches how to simulate and analyze a fatigue composite model with the help of UMAT Subroutine in Abaqus software. In this training package, we have provided all the files needed for your training, including articles, theories, how to write subroutines, and software settings.

Composite Pressure Vessel simulation in ABAQUS

 420
This training package professionally provides tips for designing and simulating composite pressure vessels. In this package, various winding methods of simulation methods of composite pressure vessels are presented. This training package teaches scripting for automatic simulation of composite pressure vessels with three methods of geodetic,isotensoid, and planar winding. UMAT subroutine is also examined to identify the failure initiation and continuation of the failure based on a PUCK criterion.

Additive Manufacturing or 3D Printing Abaqus simulation

 440
3D printing or additive manufacturing simulation is the process of producing 3D parts. This technology is important because computer-aided design and 3D printing directly lead to the production of physical components.  This educational package includes two 3D printing modelling methods. The first method is based on the use of subroutines and Python scripting and was done by a team with the goal of coding all the steps of 3D printing. The second method uses the ADM plug-in to simulate additive manufacturing. This plugin is an advanced tool to simulate the 3d printing process and cover different ADM processes. It seems the best tool to simulate additive manufacturing or 3d printing up to Now!

Introduction to UEL Subroutine in ABAQUS

 210
UEL stands for User-defined Elements. When you have a finite element analysis that requires an element type that doesn't exist in the Abaqus element library, you must write a UEL subroutine. Or, when you want to define various element shape functions, the UEL would be the best choice. This subroutine is one of the most sophisticated in the Abaqus and is intended for advanced users. With this tutorial package, you can become an advanced user and learn how to write such a complex subroutine. This package contains two workshops: writing a UEL subroutine for a planar beam element with nonlinear section behavior and writing a UEL subroutine for a beam element with specific boundary conditions and loading. Watch Demo

Introduction to VFRICTION and VFRIC Subroutines in ABAQUS

 130

This tutorial help you in cases where the classical Columbian equations are more complex and cannot be implemented by the graphical ABAQUS environment. This package introduces and teaches how to write these two subroutines. This introduction contains explaining different optional and mandatory parameters of VFRICTION and VFRIC subroutines.
