VUMAT in ABAQUS

Submitted by arabali83 on

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

damage to fracture (formation and propagation of the discontinuity)

Submitted by saeedhatefi on

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.

Shear waves, medecine and brain

Submitted by tlaverne on

 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
