Cyclic Plasticity of Additively Manufactured (AM) Metals: Experimental Investigation & Constitutive Modelling
Dear IMECE Attendees:
The Applied Mechanics Executive Committee (AMD-EC) is pleased to announce the 2016 IMECE student travel award and best paper competition.
Hi
I want to simulate experimental result of a CFRP [45/0/-45/90]s single lap joint in ABAQUS.
I have given geometry, properties & graphical result in the uploaded images.
Yellow color plate in the joint geometry is the E-Glass end tabs to grab both the ends
of the joint in the hydraulic grips. The loading(shear) is carried out at 0.5mm/min.
Thichness of each ply is 0.12mm; so thickness(T) of one CFRP plate is 0.12*8 = 0.96mm.
Thickness of adhesive layer is 0.15mm.
Overlap length(L) is 10mm.
Hi
I amtrying to model a simple compression test om a foam cube with LS DYNA. I have tried a lot of different approaches but there is always something wrong in the model :(. I have managed to get on model up and running, but i am having problems with excessive penetrations! Do anyone have any idea how to fix this?
I have includef the .k file as a text file to this post.
I set up this model of a shaft with to opposing torque simulating a shaft and pulley system.
The supports and loads are shown here: Ex-3-9-LoadsAndSupports.png
Note that the origin (top left) has the rotation X constrained to eliminate rigid body motion and to set a reference of zero twist at that point.
I requested every result that I can imagine, see the Outline here: Ex-3-9-Outline2.png
The torque is shown here: Ex-3-9-TorsionalMoment.png
Can someone advise me the algorithm for writing VUMAT for C-L model? I have doubts mainly in following steps.
1. Will Elastic and plastic predictor step be similar as isotropic hardening model given in VUMAT example pdf?
2. How to couple damage prediction steps?
Why ANSYS calls the well known "element coordinate system" with their own term, "solution" coordinate system?
Why ANSYS calls the well know method of applying a "bias" for mesh refinement with their own term, "inflation"? -- I looked it up. INFLATION: to cause to expand or distend with air or gas.
Why ANSYS calls the well know method of "partitioning" a solid model with their own term, "slice"? OK, may be "slice" is descriptive, but "inflation"? and "solution cs"?
