The attached notes are written for a course on plasticity. When I update the notes, I will post a link on my twitter account: https://twitter.com/zhigangsuo.
Rheology is the science of deformation. This science poses a question for every material: Given a history of stress, how do we predict the history of strain, or the other way around?
Two faculty positions are available in the Department of Civil and Environmental Engineering at University of Houston. One is in the general area of geoengineering (including geomechanics), and the other in the general area of fluid mechanics. Additional information is included in the attached advertisements.
The problems of singularity formation and hydrostatic stress created by an inhomogeneity with eigenstrain in an incompressible isotropic hyperelastic material are considered. For both a spherical ball and a cylindrical bar with a radially-symmetric distribution of finite possibly anisotropic eigenstrains, we show that the anisotropy of these eigenstrains at the center (the center of the sphere or the axis of the cylinder) controls the stress singularity.

Applications are invited for two PhD positions (four years) in the area of computational modelling in the Computational Mechanics of Materials group of the Faculty of Civil Engineering and Geosciences at Delft University of Technology in the Netherlands.
Can anyone suggest a way to reduce the mesh size within Abaqus using the odb(database) file ?
Midpoint and double step algorithms are interesting implicit algorithms for integrating the governing equations in plastic regime. Developing such algorithms for large deformation is complex due to the various configurations that have to be considered. In this paper a new algorithm is proposed for the integration of governig equations in large deformation plasticity which is based on midpoint rule. The time continuous model as well as algorithmic setup are discussed in details.
