Stress concentration at a corner of varying angles, mode I and mode II

Choose a channel featured in the header of iMechanica: 

I was looking at the stress concentration at a corner for both a mode I and mode II loading situation.

For reference, see: Carpenter, 1984. Mode I and mode II stress intensities for plates with cracks of finite opening. International Journal of Fracture. V. 26. 201-214. 1984.

The problem that is being addresses is the stress concentration found at a corner in an infine body as seen in the figure below. β=0...π.

ASME 2008 Conference Track on Mechanics of Solids, Structures and Fluids

The ASME International Mechanical Engineering Congress (IMECE 2008) will be held on October 31 - November 6, 2008, in Boston, Massachusetts. http://www.asmeconferences.org/Congress08/. A wide range of mechanics-related symposia (topics) are being organized in Track 12 Mechanics of Solids, Structures and Fluids. The Executive Committee of the ASME Applied Mechanics Division (AMD) believes that this track will provide a good platform for mechanics-related presentations.

Material model of Kevar composite for Impact problem

I am looking for material model of Kevlar composite for Ballistic impact simulation. Presently i am using ANSYS. Can any body suggest material model for kevlar composite for fracture and penetration phenomina.

ON THE MECHANICS OF HELIX

Helix is a very interesting structure. There are many biopolymers that have a helical structure. 

  • How can someone model the helix in mechanics?
  • How can the helix reinforce a rod? 
  • How does this structure reflect the mechanical properties of biopolymers?

Postdoctoral Position at Penn State University in Multiscale Computational Dynamics

We have an immediate opening in the Department of Engineering Science and Mechanics for a postdoctoral research associate in multiscale modeling and computational mechanics. The focus of this position is on the modeling, simulation, and analysis of the nonlinear evolution of coupled macro/microstructure in failure processes, with an emphasis toward structural health monitoring. Coupled-field models using continuum damage variables will be used to study the fundamental spatiotemporal features of damage evolution, particularly regarding the nature and origin of unpredictability in damage processes. The candidate must have a solid general background in theoretical mechanics and dynamics, and be familiar with nonlinear finite element analysis

Physics programmer position in Boston

The person in this position will be responsible for developing finite element-based soft tissue representations that supportreal-time interaction with surgical tools. The successful candidate should befamiliar with the extensive prior work in the field of surgical simulationincluding finite element formulations (both traditional nonlinear approaches aswell as various real-time approximations), real-time collision detection andresponse between rigid and deformable objects, multi-processor/coreimplementations, and integration with haptics devices.

Stresses and Strains

In classical elasticity, we know that at the interface of two different materials, traction stresses and non-traction strains are cotinuous. Traction stresss are continuous according to Newton's third law, but why non-traction strains are continuous?

Symposium on "Defects in materials: Theory and Applications" at 2008 ASME conference

A symposium on "Defects in materials: Theory and Applications" is being organized at the 2008 ASME conference in Boston (Oct 31-Nov6). To submitt abstracts to this symposium choose Track 12-4 (Track 12, topic 4). The abstract submission deadline is March 3, 2008. Below is the description and scope of the symposium:

Review: Coarse-grained model for normal mode analysis of proteins

The preprint provides the summary and/or review of current state-of-art in coarse-grained modeling of protein structures for normal mode analysis. This review summarizes the quasiharmonic analysis, Go model, elastic network model, and recently suggested coarse-grained models for protein structures.

Abstract 

Software for meshless....

I would like to know which software is people using for meshfree simulation. Is there any more or less "standard" one  that people tend to use?  I'm interested in knowing about any one for any kind of problem.

Immediate PostDoc Position Available: Nanocomposite Modeling and Experiments

A post-doc position is available at the University of Notre Dame in Aerospace and Mechanical Engineering. The project focuses on nanocomposite deformation modeling and performing corresponding experiments using primarily atomic force microscope and X-ray diffractometer. Initial position is for one-year and is extensible for another year contingent upon continued funding. The position offers attractive collaborative opportunities with national labs and material synthesis groups across different universities. Salary is negotiable.

ANSYS vs ABAQUS in high frequency wave simulation

Hi all,

 I want to know for guided wave simulation in composite material, ANSYS or ABAQUS will be a better choice? 

Thanks

Two postdoctoral positions available at Johns Hopkins University

I am looking for two postdocs in the analytical and computational modeling areas. One position will focus on the theoretical and computational modeling of microstructure-modulated failure processes, with an emphasis on nanocrystalline materials. The other will focus on hypervelocity impact fragmentation problems, including planetary scale impact and fragmentation. The latter position is available immediately, and the former is available as of June 1, 2008.
