Strain Rate Calculation in CEL

Submitted by sujan on

Hi!

I am trying to calculate the strain rate in Coupled Eulerian Analysis Using ABAQUS. I want to Calculate it through Plastic strain as strain rate in vuhard is not working properly. I want to fix the strain in state variable for a time period but with analysis, it is updated automatically. Is there any options to keep strain fixed for a time period?

 Any idea will be highly appreciated.

Thanks in advance.

A variational approach to predict percolation thresholds of nanomaterials

Submitted by Frankxu on

Study on the properties of inhomogeneous media plays a central role throughout the history of physics, e.g.

Possion’s theory on magnetism of composites, Faraday’s dielectric model of composites, Maxwell’s and later

Rayleigh’s work on conductivity of composites, and Einstein’s thesis on viscosity of fluid-particle media. As

a special branch of this field, percolation research on phase transition and critical phenomena was originated

with lattice percolation theories in 1950s [1]. The idealization of a lattice structure is convenient for analytical

VUMAT subroutine for kevlar in abaqus

Submitted by muzamil72003 on

Hi guys, i am new to abaqus, just 6 months using it.

Does anyone have a idea on how to  define property for kevlar fabric in VUMAT subroutine?

 My study is on ballistic impact on soft body armour. I am modelling 9mm FMJ bullet (cooper jacket with lead core) and fabric type choosen is woven fabric which is Kevlar.
