    Nonlinear material in ABAQUS

    Hi,rstupplebeen! Thanks for the help! But the hyperelastic material is uncompressible.Now I'm simulating the soil behaviour. If someone could help, maybe just some hints, I will be very grateful.

    Nonlinear material in ABAQUS

    Hey guys, I have been struggling with this problem for one week.Wish someone could help me to get over it. Thanks in advance! I want to make solid element have nonlinear property. For example, the solid element has Elastic Modulus E1 during displacement interval 1, and it has another Elastic...

    Mohr-Coulomb

    Hi,guys! I'm using solid element for the simulation of the mutilayers of the railway track.I want to use Mohr coulomb plasticity to define the material properties for the ballast,subballast and the subgrade layers. The question is now I only have the Cohesion c and Friction angle for each...

    Steady state dynamic

    Hi,Friedmind!Thanks for your help!:) What you said is also what I'm secretly hoping is correct.But until now I still can not convince myself about that.The reason is : The receptance, which is the dynamic diplacement per applied force, should be a curve that all the value is positive. But...

    Steady state dynamic

    Dear Guys, I have a question about the steady-state dynamic step. I'm looking for a digram that Y-axis is the structure receptance,which is the displacement over the force put on it;and x-axis is the frequency rang that I'm interested. What I did is apply a concentrated load at the structure...

    Define a sinusoidally varying load

    Dear all! I have been hunted by this question for a long time. Wish I could have the luck to get some helps from here. Thanks in advance! I'm analysing a structure's dynamic response due to a sinusoidally varing force. The force is like: F=sin(wt) But the 'w' here needs to...
