Abaqus VUMAT for hypoplastic law
Please, I’m investing about the hypoplastic model for granular materials to study the behavior of sand under a dynamic excitation. I try to use the UMAT – VUMAT interface, Interface between UMAT (Abaqus/Standard) and VUMAT (Abaqus/Explicit) from http://www.soilmodels.info/ node17.html website.

Looking for postdoctoral position.
Hi Dear prospective supervisors
Im TEMO. I have recently been awarded PhD in Mechanical Engineering, particularly in computational mechanics. at the University of Kwazulu-Natal in South Africa. My research includes the numerical study of the vibration, buckling of composite plates, nanobeams and nanoplates aswell as the study of optimisation of beams and plates subjected to various forces and flowing fluids. My numerical expertise includs DQM, FEM, FDM...

Symposium Description:
problem about the Jacobian matrix (DDSDDE) in UMAT
Hi all friends,
I have a question. Why the Jacobian matrix (DDSDDE) in UMAT is defined as:
∂Δσ/∂Δε
rather than:
∂σ/∂ε
And can anybody tell me what's the difference between them?
Thank you all for your help,
Tianhao Yan
vtk.js vs. three.js
vtk.js is a recently released javacript version of vtk. Here's my experience with it and how it compares with three.js today. http://www.parresianz.com/javascript/typescript/vtkjs/threejs/vue/vtkjs-ellipsoid/
