    USDFLD routine with built-in VUMATs

    Hi there, I'm modeling a ceramic plate using the Johnson Holmquist material model which is available as a built-in user material for Abaqus (i.e., via a VUMAT subroutine that is built-in and whose source code cannot be edited). The material model is called in the input file as below...

    How to define a RADIAL distributed load on an internal edge of a shell

    Hi, I'm modelling a circular beam as shown in the figure below. I'm trying to apply a radially distributed load (aka "normal" traction) on an INTERNAL edge (at r=2) of units Force/Distance. I can't apply a shell edge load since this edge is internal. When I apply a Pressure load, I get an...

    USDFLD-Modelling functionally graded materials in ABAQUS

    Hi Bartosz, Thank you for pointing out my mistake! I incorrectly assumed that Abaqus would use the same interpolation that it uses within the FV range specified (of 1-2) to extrapolate outside the FV range. However, as you mention, Abaqus uses a CONSTANT extrapolation outside the range of...

    USDFLD-Modelling functionally graded materials in ABAQUS

    Hi Bartosz, For some reason, when I use the file sharing service provided by Engineering.com, I get an upload error. Instead, I'm providing a google drive link: https://drive.google.com/file/d/0B7-zIaLPMZRxM2p5c3RHdXBaSFk/view?usp=sharing I hope this will work. I've attached the input file...

    USDFLD-Modelling functionally graded materials in ABAQUS

    I'm trying to model a simple beam with the Young's modulus varying with position. I've followed all the instructions for the USDFLD detailed by akabarten in the posts: http://www.eng-tips.com/viewthread.cfm?qid=385982 and http://www.eng-tips.com/viewthread.cfm?qid=295995 The relationship...
