abaqus
Hi
i want to add a stress relation to abaqus
can i write it in fortran in a way that i can enter specification like c11-c12-....in abaqus then have the calculation of stress in fortran and bring back the result in abaqus to analysis?
how to convert umat to vumat
hi every body
i want to model microforming processes using crystal plasicity,,, i have Dr huang single crystal code writing in umat inteface,,, i want to model some forming processes i abqus/explicit so i should write or convert above code to VUMAT code ,
can anybody guide me how to do it?
any help would be appreciated
Postdoctoral Researcher in Computational Mechanics of Composite Materials at IMDEA Materials
The research group of Structural Composites at IMDEA Materials (Madrid, Spain), led by Dr. Cláudio S. Lopes and Dr. Carlos González, invites applications for a Postdoctoral Fellow in the field of multiscale computational analysis of composite structures. Candidates with strong background knowledge on computational damage mechanics, model development, and on numerical simulation of advanced composite materials and structures are strongly encouraged to apply. Experience in experimental mechanical testing of composites is highly valued.
relation between the Euler-Lagrange strain tensor and the 2nd Piola-Kirchhoff stress tensor
At finite deformations, the 2nd Piola-Kirchhoff stress tensor S_{IJ} is work-conjugate to the Euler-Lagrange strain tensor E_{IJ}, i.e. the work done by the stress S_{IJ} at developing a strain E_{IJ} per unit volume in the reference configuration is
W = 1/2 S_{IJ} E_{IJ} (Einstein summation over repeated indices implied)
I would like to express this in the same form as used in linear elasticity, i.e. to write S_{IJ} = M_{IJKL} E_{KL}, which would give me
W = 1/2 M_{IJKL} E_{IJ} E_{KL}
How can a zero length torsional spring element be modeled in ANSYS?

Hello
brothers
Currently,
I‘m working on the determination of the mechanical properties of carbon nanotubes
for different loading cases using ANSYS software ( i need to use them in my
model). My Finite Element model of graphene and carbon nanotube is working fine with beam188 element, but I have
some technical problems in my simulation. These problem are summarized in
points as follow;
