I am doing my thesis and my topic is hypervelocity impact testings on foils.
Can anyone suggest me which software will be quite useful to perform simulation for my thesis.
LS-DYNA- Abaqus- AUTODYN. And where i can find related materials to start up with these software.
I find it quite confusing and since on internet for LS-DYNA & AUTODYN, less materials are available.
Thanks
I am modeling a plate under three point bending with Abaqus. The plate
is a sandwich structure with aluminum plate (thickness: 5mm), adhesive glue (thickness:
0.02mm) and a kind of foam (thickness: 15mm) bonding together. Their Young’s
modulus is at the order of 100GPa, 1MPa and 100MPa. While in incremental
calculation, the job is always be aborted for not achieving convergence. I just
wonder whether the cause of not achieving convergence should be attributed to
the huge difference in Young’s modulus.

Position is available for a postdoctoral fellow to carry out an industry sponsored project on carbon fiber composite modeling. The contract is initiated for one year, with possible extension if work progresses satisfactorily. The research will focus on
(1) micromechanics modeling of elastic and viscoplastic behavior of injection molded carbon fiber composites;
(2) homogenization techniques and constitutive model development for vibration, strength and impact simulations of carbon fiber composites.
Hello,
I am working on my master's thesis. I have to find best fitting hyperelastic material model for simple shear test.
My task is to find most proper material model which will fit my laboratory test data. I have conducted the "single lap test" on bricks, using polymer PS.

Molecular dynamics (MD) and density functional theory (DFT) studies were performed to investigate the influence of vacancy defects on generalized stacking fault (GSF) energy of fcc metals.
Hello All,
Currently,I am modeling elasto-plastic buckling of laminated composites. I started with 3 layers (fiber-matrix-fiber) respresenting unit cell of composite. The model is made with material non linearity and incremental approach - Modified Riks Algorithm has been used for buckling analysis. My try would be to get plastic buckling in the model. For this I need to introduce "Element Weakening Method" (EWM) which allows user's choice to assign weak properties or reduced stiffness to the selected elements. Consequently, this helps in propagating damage.
