Geostatic procedure for partially saturated soil
Dear collegues,
I do geostatic procedure for partially saturated soil.
ABAQUS is used.
The model of soil - Cam-Clay.
Initial stresses in the soil are given.
The initial pore pressure as well set.
Material data is fully specified.
Nevertheless - the program displays an error message:
The sum of initial pressue and elastic tensile strength for the porous elastic material in element 1 instance full-1 must be positive.
May be somybody knows the reason of the message?
Post-doc position on computational mechanics at IMT Lucca
A new post-doc position (1 year renewable up to 3 years, till the end of the ERC Starting Grant Project CA2PVM, http://musam.imtlucca.it/CA2PVM.html ) is open in the Research Unit MUSAM - Multi-scale Analysis of Materials ( http://musam.imtlucca.it ) directed by Prof.
Transverse shear stresses in Reissner Mindlin theory
How is it possible to obtain the transverse shear stresses correctly, not constant, by Reissner Mindlin theory?
Equilibrium equation would be the first solution, but, once the second derivatives of bilinear shape functions are zero, no results is appeared.
Thanks in advance for any help!
writing UHARD subroutine in ABAQUS - power law hardening
Hello All,
I am required to incorporate the simplest form of constitutive law - elasto-plastic material with power law isotropic hardening in ABAQUS.
Does any one know where to look for tutorials on writing UHARD in ABAQUS?
Any help would be appreciated.
Thanks,
Jay Patel
Two Post Doctoral Positions in Advanced Synthesis and Characterization at Rice University
Position Description: Two postdoctoral associate positions in the area of advanced synthesis and nano/micro-scale characterization of nanoparticles are available at Rice University. Various techniques will be applied to synthesize and self-assemble size- and shape-controlled silicate nanoparticles followed by nano- and micro-characterizations including a myriad of probes such as electron microscopies (TEM, XRD, SEM, AFM), ICP, XPS, NMR, porosimetry, dynamic mechanical analysis, nanoindentation, etc.
Virtual Special Issue: 'Outstanding research contributions in the area of nonlinear continuum and computational mechanics'
The 2014 Nathan M. Newmark Medal was awarded to Professor Herbert A. Mang at the annual ASCE Structures Conference, which took place in Boston, April 3–5, 2014. Professor Mang was awarded the Newmark Medal for his outstanding research contributions in the area of nonlinear continuum and computational mechanics that clarified the cause of collapse of important concrete structures and quantified the influence of the initial post buckling behavior of metallic structures.
X-DMS Conference
You are cordially invited to attend X-DMS 2015 which continues and replaces the successful X-FEM conference cycle (Achen 2009, Cardiff 2011, Lyon 2013) and aims at including a wider variety of methodologies coming from different areas of computational mechanics and numerical analysis.
