Various outcomes of slip-coherent twin boundary depending on the stress state and slip geometry (during the growth of a microstructurally short crack)
The Cardiac Biomechanics Laboratory at the University of California San Francisco Medical Center (UCSF) Division of Cardiothoracic Surgery and San Francisco VA Medical Center is seeking a hard working, motivated post-doctoral fellow to participate in biomedical engineering research involving the ascending thoracic aortic aneurysms (aTAA). The post-doctoral fellow should be motivated to be on a career track to become an academic professor. Our lab is NIH funded to investigate the biomechanics of aortic aneurysms and currently has 2 postdoctoral fellows, and are seeking a 3rd.&nbs

Introduction
With funding from the Haythornthwaite Foundation, the Executive Committee (EC) of the Applied Mechanics Division (AMD) of ASME is pleased to announce the establishment of the Haythornthwaite Research Initiation Grant Program, targeting university faculty engaged in research in theoretical and applied mechanics that are at the beginning of their academic careers. Applicants must hold a tenure‐track appointment at the rank of Assistant Professor at a US university on October 1, 2016, and must not be more than 5 years beyond receipt of their doctoral degree at the time the award is made.
I was wondering if anyone knows of an analytic Solution for KI and/or KII in tubes.
I´ve seen an infinite number of equations, shape functions, FEM simulations, standards, etc. But one closed solution for tubes?, an analog to Williams series but for cilindirical surfaces?
Friction and deformation in granular fault gouge are among various dynamic interactions associated with seismic phenomena that have important implications for slip mechanisms on earthquake faults. To this end, we propose a mechanistic model of granular fault gouge subject to acoustic vibrations and shear deformation. The grain-scale dynamics is described by the Shear-Transformation-Zone theory of granular flow, which accounts for irreversible plastic deformation in terms of flow defects whose density is governed by an effective temperature.
Hi I am getting this error message while running a UELMAT:
The ESIS Technical Committee 24 provides a forum for researchers and engineers who deal with structural integrity problems in modern railway system. During our latest meeting, held on 1-2 October 2014 at Politecnico di Milano, excellent talks presented results obtained within different research projects, including EURAXLES - EBFW3 and SUSTRAIL.
Hello,
I have implemented a linear viscoelastic model using the user subroutine Usermat in Ansys.
I have used the classical paper: "Formulation and implementation of three-dimensional viscoelasticity at small and finite strains" of Kaliske & Rothert (Simo's approach) and it works fine for small deformations.
It is written in the documentation that in the case of a simulation with large strain (geometric nonlinearity), one must rotate the state variables.
