i working on impact, and I should model the penetration in armour, last time i modeled it by LS -DYNA and now I working with abaqus, but it does not have material model for ceramic. accordingly, i should write the VUMAT, but i do not know how I start.
I need some reference for starting to write subroutine. please help me
hello,
I am working on modeling of Continuum damage in isotropic materials. I have written a Matlab code for modeling of a continuous damage and I have verified it with several examples. In this modeling, I have mesh-size independent through the smeared damage model. Now, my aim is to present a continous-discontinous model.
Please see the attached file for details.

Usually ultrasound equipment in medicine only use compressional waves.
But since human tissues have a high bulk modulus, the P-wave speed is
relatively constant (around 1580 m/s). Human tissues are very stiff if
you apply isotropic constraints on them (like pressure of water).
However M. Fink and his colleagues proposed a new way to investigate
human tissues by first sending a strong compressional wave in the tissue
that is able to make ripples in the body, then shear wave are produced

Hi, everyone!
I will employ the meshfree method in order to analyze the composite model including the spherical filler and matrix.
However, if the background cells are regular reluctantly, there will be background cells where two types of materials coexist.
In this case, I don't know how to calculate the integral form, K=int_V B'CB dV, numerically.
