    simple problem with UMAT

    Hello Dears! could you help me please. I wrote a small umat subr, but it works doesn't correctly I have 2 steps Dens=7800 for Emodulus i use next eq. E=Dens**2.5 at first i define DDSDDE, stess, strain, strain energy denity, and parametr S if S < some value then Ddens=7800 and then...

    Moving pressure with DLOAD subroutine

    Mr. Bartosz, Dear Sir! I mean dynamic analysis in Abaqus/Explicit! I simulate railroad tracks for dynamic analysis see no reason to use a moving load in static analysis could you show an example of using VDLOAD, I would be very grateful to...

    Simple problem &amp; subroutine &amp; usdfld

    Thank you so much, Mr. akabarten. It helped me. The main task - to build bone model with variable over the thickness elastic modulus. In the article (http://www.asbweb.org/conferences/2010/abstracts/102.pdf ), I saw something similar but for the density there also used usdfld What do you think...

    Simple problem &amp; subroutine &amp; usdfld

    I'm trying to simulate a plate with different thickness elastic modulus. I use subroutine and usdfld For a rectangular plate I did. But for a circular plate need to use a cylindrical coordinate system, because I want to simulate a different modulus of elasticity in the radial direction I...
