Simulation of the Quasi-static Crushing of a Fabric Composite Plate is a methodology for modeling the crushing behavior of composite structures using
Abaqus/Explicit. Very good quantitative and qualitative agreement between the
numerical results and experimental data is shown, demonstrating the utility of
Abaqus/Explicit for assessing the crashworthiness of composite structures and
reducing the amount of costly experimental testing.
An automated Isight optimization workflow for the calibration of material
parameters is presented. Using component models from the Abaqus Worldwide Side
Impact Dummy (WorldSID) we will validate one of the calibrated material
parameters by comparing the response of several dummy sub-assemblies with
Fluid-Structure Interaction Analysis of a Prosthetic Aortic Valve using Abaqus/Explicit Smoothed Particle Hydrodynamics - 2012Submitted by SIMULIA on Thu, 2012-09-20 18:56.
The smoothed particle hydrodynamic (SPH) analysis method in Abaqus/Explicit
overcomes this difficulty. In this Technology Brief, the SPH
technique will be used to determine the FSI response of a generic prosthetic
Abaqus/Standard Coupled Simulation of Thermally Assisted Gravity Drainage of an Oil Sand Formation - 2012Submitted by SIMULIA on Thu, 2012-09-20 18:47.
Abaqus/Standard provides an analysis capability that allows for coupling between
heat transfer, pore fluid flow, and displacement. We demonstrate how this capability can be used to simulate the thermally
assisted gravity drainage of an oil sand formation.
Hot rolling is a basic metal forming technique that is used to transform
preformed shapes into final products or forms that are suitable for further
processing. The important aspects of this manufacturing operation are the
elongation and spread of the material during the rolling process.
A fully coupled fluid-structure interaction analysis of a wind turbine rotor is
presented. Abaqus/Standard and STAR-CCM+ are directly coupled through the
SIMULIA co-simulation engine. With this approach, a high fidelity modeling
strategy can be used to develop an accurate understanding of the blade dynamics.
Simulation of the Ballistic Perforation of Aluminum Plates describes Abaqus/Explicit modeling of the ballistic impact of metal projectiles
on metal targets. It will demonstrate the utility of Abaqus/Explicit as a tool
for reducing the amount of experimental testing as well as assessing the
projectile residual velocities and time-resolved kinematics.
Pipeline Rupture in Abaqus/Standard will be used to predict the burst pressure of a steel pipe-line
with a notch-type defect. A ductile damage initiation criterion is used, and
favorable comparison with available experimental data will be shown.
It is a methodology for building a coupled electromagnetic and fluid-structure
interaction analysis of a solenoid valve. A seamless integration between the
applicable analysis techniques allows for the simulation of the complex

I'm trying to figure out how the Interaction Module (surface-to-surface contact) in ABAQUS works. I want to apply a compression force on a 2D axisymmetric
deformable body via an analytical rigid surface(2D and axisymmetric also) - basic stuff. When I launch my simulations,
I get the good strains and stresses at the surface of the body which is in contact with the analytical rigid. Moreover, the reaction
forces and displacement of the analytical surface are adequate.
However, when I look at the reaction forces of the nodes at the surface of the body, they are null. Obviously this is false
since I should obtain the same results (opposite direction) as the reaction forces of the analytical rigid surface. Even more strange
I want to model a soil body which its shear modulus changes with the deviatoric strain.I know it can be introduced in ABAQUS by field variables (defining a field variable). But the question is that how can I tell ABAQUS that the defined variable is the "deviatoric strain" ?
Thank you beforehand.
I am trying to analysis a model in ABAQUS with a plate bolted to the Bracket top surface at 4 ends. I have to define contact between them (and also bolted at 4 ends) to get the Modal frequency. But When I searched for it, I got the answer that contact doesn't work with Modal analysis as contact is a nonliner problem and Modal Analysis only solves linear problem.
I am trying to model flexure of a material with softening stress-strain response. How can I model that! I know Abaqus can not handle negative tangent modulus. And, how do I simulate damage in the beam!
Any help/suggestion is highly appreciated!
In Abaqus Theory Manual 4.6.1, there is a concept called "effective deviatoric elasticity". I think that term is actually DDSDDE, i.e. the consistent linearized tangent moduli.
But why is it called "effective DEVIATORIC elasticity"? It sounds like we missed the volumetric part (but only considering the isochoric part).
I would really appreciate it if someone could help me with this. Thanks!
I have been writing a UMAT function with modified hyper-visco-elastic model. My question is: after I got the Cauchy stress at the end of step, how do I get the SSE （elastic strain energy density)?
I am very new in Abaqus. I want to learn abaqus as well do some
simulation of machining (Orthogonal/oblique). So I am looking for a
I have searched in google, but there is no such specific tutorial for machining. So, If anybody have any such tutorial please please forward me in my mail ID: firstname.lastname@example.org.
It will be very great help for me. Or, any site that provides basic
steps in Machining simulation in abaqus that also do. thanks in
im working on an abaqus model which should be meshed by AC3D4 acoustic tetrahedral elements.
i attached the picture of main meshed model and my model .
but there is a difference between them. ( i pointed them by white areas)
how can i mesh o control mesh to create that kind of meshing
top model is mine and bottom is original model.

Problem description: There is a simply supported(roller supports) shell element I-beam. There are lateral bracings too. All of this boundary conditions belongs to the Riks step(always last step in analysis).
Question: I have implemented triangular residual stresses by SIGINI subroutine, but I'm not sure what boundary conditions set up in preliminary equlibrium step. Should I include all of the lateral bracings in this step or maybe only roller support?
I am trying to run some simulation in abaqus, I need to change some input variables and run the code for new values and this should be an automatic process not by hand every time.
Now I want to check if there is any way to change some parts in a abaqus .inp (input) file (say the Forces or other BC's) and execute the code again in abaqus and store the results of each simulation.

I want to simulate the deformation of breast under gravity. I
initially have patient's breast images in one position (supine, with
breast falling on the chest). I want to apply gravity loading and
simulate breast image in another position (prone, with breast falling
away from the chest).
I follow the standard path i.e. segment images (supine data),
generate mesh, import the mesh into ABAQUS, apply material properties,
BCs and loads and run the simulation and I get deformed breast mesh
