The Research Center for Mechanics of Solids, Structures and Materials at the University of Texas at Austin invites applications for an open position as Post-doctoral Fellow. The specific project involves the characterization of the constitutive and failure behavior of structural materials (aluminum alloys, steels, titanium alloys, metal-matrix composites, polymers and other selected materials) under quasi-static and dynamic conditions. Candidates with a strong background in mechanics of solids and structures, and with experience in experimental, and numerical characterization of material response are invited send their resume and list of references to: Prof. K. Ravi-Chandar (ravi@utexas.edu). This position is available immediately.

Dear friends and colleagues,

This is to inform you of the minisymposium

Plasticity: Bridging the Scales from Micro to Macro

to be organized at the 22nd International Workshop on Computational Mechanics of Materials (IWCMM XXII) and request you to consider submitting an abstract. The workshop will be held in Baltimore, MD, USA during September 24-26, 2012.

Dears,  I am quite new in the area of Abaqus models and biomechanics. My background is related with textiles. However I am a post doc in Belgium at the moment and my new task is to model a fingertip skin section under the influence of contact with different objects.

Energy harvesting is the process of converting energy that will otherwise be dissipated into the ambient environment, into useful energy to do work.  I shall focus this discussion on motion-based energy harvesting.  Motion-based energy harvesting is the process of converting dissipated mechanical energy into electrical energy.  Sources of mechanical energy include the ocean waves, wind, human motion, vehicular traffic, and vibrations in buildings and bridges.  This source of energy is ubiquitous and pervasive, and yet, it is one of the least developed energy harvesting technology.

The deadline for abstract submission for the 32, 10th April 2011, is approaching. The title of the 32nd Risø International Symposium on Materials Science is "Composite materials for structural performance: towards higher limits". The Symposium will be held from Monday 5th September to Friday 9th September 2011 at Risoe DTU - National Laboratory for Sustainable Energy, Technical University of Denmark, 4000 Roskilde, Denmark. We think this is an exciting Symposium theme and we are proud to present a great list of key-note presentations:

Brian N. Cox (Teledyne Scientific Company, USA)

I'm trying to plot the stress-strain curve described by the Johnson-Cook strength (and eventually damage) models. The strength model is defined as:

σ=[A+Bεn][1+C ln(ε_dot*)][1-T*m]

where A, B, C, n, and m are material constants, ε_dot* is the non-dimensionalized strain rate, and T* is the homologous temperature where T*=(T-T0)/(Tmelt-T0)

To calculate the thermal softening (term in the last bracket of the J-C model), I need to determine the increase in temperature related to an increase in stress (and strain). I'm using the following equation:

ΔT=∫ Χ (σ/(ρ*cp)) dε

Seeking a postdoctoral candidate with experience in atomistic/molecular simulation for a two-year position. 

Areas of investigation will include:

Does anyone who has previously worked on MSC Marc worked with the concept of element activation and deactivation...?

I need to do a simulation wherein a hole is required to be punched in an alloy steel bar.

The issue is that I am not sure as to how to go about this.

If there is anyone who can guide me through this ..I would appreciate it..!!

Regards,

Krunal.
