Look for free-code UMAT on polymer viscoplasticity model of M.C. Boyce

Submitted by Liu Jinxing on

I just attended USNCCM11, and heard from a presentation that there should be free code for polymer viscoplasticity model from M.C. Boyce.Unfortunately, I googled from half an hour and dowloaded nothing this afternoon. Can anybody give more info ?

Thanks in advance !

Modeling contact problem in ABAQUS

Submitted by drmaity on

Dear all,

In my FE model (pin on disc), I would like to define a contact property between pin and disc with a friction defination available in ABAQUS. I have assumed that friction coefficient depends on parameters like slip rate, pressure and temperature only. When i used friction coefficients with slip rate and pressure, model works without any error but if i use friction coefficients with slip rate, pressure and temperature, the model doesn't work and come up with following errors;

cyclic loading

Submitted by danielteruna on

Dear All

I want to input data for cyclic loading in abaqus. The input data are equivalent stress and strain.

Can any one to help me how to get equivalent stress and strain from uniaxial tensile test.

thank yiou for any help

Designing Safer Vehicles with Realistic Simulation of Airbag Deployment

Submitted by matt.ladzinski on

Airbags are one of the major protection systems used in a car crash. They play one of the most important roles in preventing severe injuries and fatalities during vehicle crashes. The advancement of new technology and airbag regulations necessitates that airbags be tested for safety in all kinds of scenarios, including situations where the occupant interacts with the airbag before it is fully deployed.

Water Landing of Space Flight Re-entry Vehicles Using Abaqus/Explicit

Submitted by matt.ladzinski on

Space flight re-entry vehicles need to withstand heavy impact upon landing and it is critical for engineers to understand the effects on the vehicle and the crew to ensure the safety of the mission.  In order to gain this insight, engineers need to be able to model both the space craft structure and the landing medium such as water, sand, clay, etc.
