PhD Dissertation Position in Dynamic Failure of Advanced Materials at Northwestern University
Description
Applications are invited for a research assistant position within the Micro and Nano Mechanics Laboratory in the Department of Mechanical Engineering, Northwestern University. The successful candidate will join a vibrant interdisciplinary research group and be involved in projects addressing multiscale experimentation and modeling of advanced materials. We seek a motivated, talented and independent individual interested in conducting research on the characterization of material instabilities and failure.
A theory of constrained swelling of a pH-sensitive hydrogel
Many engineering devices and natural phenomena involve gels that swell under the constraint of hard materials. The constraint causes a field of stress in a gel, and often makes the swelling inhomogeneous even when the gel reaches a state of equilibrium. To analyze inhomogeneous swelling of a pH-sensitive gel, we implement a finite element method in the commercial software ABAQUS. The program is attached here. Contact Shenqiang Cai (shqcai [at] gmail.com) for a description of the program.
Dear Omid and Sepehr
I think a non-zero entry in the stiffness matrix doesn't necessarily imply dependence of ith DOF on the jth DOF. This is the case also for standard FEM (without any enrichments). For example for a quadrilateral 2D element the x component of displacement has interaction with y component at each node, but as we know, two independent values of translation in x and y directions can
Looking for a Post-Doc position in Geomechanics, in Europe
Dear all,
My name is Adrien Haxaire. I am currently Associate Professor at LGCIE, INSA Lyon, France, until end of August. I am looking for a
Post-Doc position in geomechanics in Europe.
During my PhD, I developped a thermodynamical model capable of describing coupled THMC phenomena in unsaturated porous media. It was implemented in Cast3M.
I am very interested in chemical reactions in porous media, their modelling and implementation. I am also interested in the field of CO2 sequestration.
what is the proof of vector addition of forces
what is the proof of vector addition of forces, actully how two vectors are added acccording to triangle parellelogram laws , actully i know the process but what is the source or origin of that rule who devised that and how please tell!

Parabolic distribution of shear stress
Hi all
According to Timoshenko beam theory shear stress is distributed uniformly across the cross-section depth which is contrary to real distribution of shear stress i.e parabolic distribution. I know there is a shear adjusment factor (5/6 for rectangular cross-section) can solve this problem. But I don't know how can I utilize this adjustment factor in the beam formulation to get parabolic distribution.
Could anybody please help me?
Regards
