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

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, this subroutine includes gradual progressive damage based on the energy method. This complex subroutine could be used for static and dynamic problems.

ABAQUS for beginners (Mechanical Engineering)

In this training package, which is designed for beginners in mechanical engineering, various examples in the most widely used fields are presented. These examples are provided with the necessary points and theories for simulation. With this training package, you will be able to get acquainted with different ABAQUS modules in the form of various examples in modeling, how to get the output and the necessary results for reporting.

ABAQUS Sequential Solution Software

With this Batch file, you can program multiple jobs in ABAQUS. So, they can be executed sequentially and do not need to be handled individually or run concurrently, which can cause software malfunctions. It can be so cost and time effective.

Additive Manufacturing or 3D Printing simulation in ABAQUS

This training package simulates 3D printing using python scripting, modeling is done layer by layer and automatically. Due to the complex equations of material behavior, UMAT subroutine is used and DFLUX subroutine is used to apply thermal conditions.

Advanced UMAT Subroutine (VUMAT Subroutine)

This training package helps Abaqus users to prepare complex UMAT and VUMAT subroutines. This training 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

Composite Fatigue Simulation with Subroutine in ABAQUS Part1

Fatigue analysis in composite materials is one of the most widely used applications in today's industry. Investigating this fatigue behavior for composite materials has many complexities and uncertainties. Scientists have tried to predict the fatigue behavior of this material at different loads by presenting various theories based on laboratory results. In this training package, by presenting the existing theories in this field and implementing them in the subroutine, it is possible to predict the fatigue behavior of composite materials and to teach you the necessary training for training as well as model upgrading.

Composite Pressure Vessel in ABAQUS

This training package professionally provides tips for designing and simulating type 3 and 4 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, semi-geodetic, and planar winding. UMAT subroutine is also examined to identify the failure initiation and continuation of the failure based on a PUCK criterion.

Concrete reinforcement and column beam joint structures in ABAQUS

Today, modeling structures with concrete, reinforcements, as well as beam and column joints are of great importance. This training package presents theories as well as various points of simulation of these structures.

DFLUX Subroutine (VDFLUX Subroutine) in ABAQUS

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. This training package with different examples in different fields tries to teach the use of this subroutine. Examples of this package welding, hot forging forming and etc.

DISP and VDISP Subroutines in ABAQUS


This package are used to describe displacement, velocity or acceleration, which are complex and functional. ABAQUS features cannot be sufficient for problems with location-dependent and time-dependent boundary conditions simultaneously. In these cases, this subroutine can be useful to solve the challenges.

DLOAD and VDLOAD Subroutines in ABAQUS


This tutorial teaches how to use DLOAD and VDLOAD subroutine in ABAQUS to define a distributed nonuniform load. To do this we explain the subroutine blocks and its definable variables and capabilities to create complex loads. Then, we simulate a simple nonuniform load example which is depending on the location, and then develop it to complex one, step by step to depending on time and etc.
