Questions About The Relation Between Mindlin's Strain Gradient and Eringen's Nonlocal Linear Elasticity Theories

Here are some definitions which I have in my mind about the hierarchy of field theories of any kind. Please read them and correct me if there is any misunderstanding. Then I shall raise two questions based on this model of thought about the Mindlin's strain gradient and Eringen's nonlocal linear elasticity theories.

Post-Doctoral Position in Molecular Dynamics Simulations and/or Discrete Dislocation Dynamics Simulations of High Entropy Alloys at Johns Hopkins University

We are soliciting applications from outstanding candidates for a postdoctoral research position in the Computational & Experimental Materials Engineering Laboratory, at the Department of Mechanical Engineering, Johns Hopkins University starting immediately.

The position is available immediately and applications will be reviewed until position is filled. This will be a one year position renewable depending on performance.

Thermally induced residual stress

The residual stress that I am talking about is mostly tensile and thermally induced. The stress is observed on the surface only upto a very small depth in the thickness direction. Is this kind of stress significantly damaging from a fatigue perspective?

Also, what would be effect of the residual on the strength?

Is it possible that some sort stress relaxation could occur and the residual gets dissipated?

Simpleware Talk at U.S. SkyScan Micro-CT Workshop, Aug 23-24 2018

Kimpton Hotel Monaco, Philadelphia, PA

The U.S. SkyScan Micro-CT Workshop, hosted by Micro Photonics and Bruker MicroCT, brings together micro-CT imaging experts and users to share knowledge and experience in advancing methods and technology for micro-CT. The event will provide interactive sessions, as well as instructive presentations on computed tomography, analysis techniques, SkyScan products, and preparing SkyScan image data with Simpleware Software.

Membrane, bending, peak, total stress

What is the significance of these stresses from strength and fatigue perspective. Are these stresses still relevant for results interpretation? Is there a possibility of misinterpretation when using these in gas turbine assesments (or complex designs with thermal and mechanical loading)?

Modeling Soil around pipeline with stiffeners in abaqus

I never worked with stiffeners in abaqus and now I should use theme. I want to model soil around pipeline with stiffeners. The stiffener behavior has 3 nonlinear components (x,y,z direction).

Crack Growth Resistance in Metallic Alloys: The Role of Isotropic Versus Kinematic Hardening

We have always modelled crack propagation under monotonic/static loading in metals assuming isotropic hardening. However, we show that anisotropic/kinematic hardening effects play a significant role due to non-proportional straining with crack advance; the isotropic hardening idealization leads to steady state fracture toughness predictions that could be 50% lower. I hope that some of you find this work interesting.
