Submitted by Anna G on Mon, 03/26/2012 - 08:34 ABAQUS step Young modulus Hello, Does anybody know how change part material during caluculations (between steps) in ABAQUS. I need to modifie Young modulus of one part in my calculations after first phase of loading. Thank You in advance Anna Frank Richter UMAT Get the file http://imechanica.org/files/Writing User Subroutines with ABAQUS.pdf (it may show up as http://imechanica.org/files/Writing%20User%20Subroutines%20with%20ABAQUS.pdf) and pick the code for rewriting ELASTIC as UMAT. Then include an if-statement in the UMAT according to the step parameter KSTEP. Provide a pair of (Young's modulus, Poisson's ratio) for each step. In step 1: EMOD=PROPS(1) ENU=PROPS(2) In step 1: EMOD=PROPS(3) ENU=PROPS(4) Good luck Frank ------------------------------------------ Ruhr-University Bochum Germany Log in or register to post comments Mon, 03/26/2012 - 08:50 Permalink Anna G Thank You very much for Thank You very much for help.

UMAT
Get the file
http://imechanica.org/files/Writing User Subroutines with ABAQUS.pdf
(it may show up as
http://imechanica.org/files/Writing%20User%20Subroutines%20with%20ABAQUS.pdf)
and pick the code for rewriting ELASTIC as UMAT. Then include an if-statement in the UMAT according to the step parameter KSTEP. Provide a pair of (Young's modulus, Poisson's ratio) for each step.
In step 1:
EMOD=PROPS(1)
ENU=PROPS(2)
In step 1:
EMOD=PROPS(3)
ENU=PROPS(4)
Good luck
