Microplane modeling of shape memory alloy tubes under tension, torsion, and proportional tension–torsion loading

In this paper, a phenomenological constitutive
model based on microplane model is used to simulate tension, torsion and proportional tension-torsion on NiTi thin-walled tube. Validation of the
microplane model against experimental results in different loading conditions demonstrates
the capability of this approach.
This publication will benefit the numerical and experimental study on SMAs.

Modelling tensile simulation including necking

HI,

 i am new in using ABAQUS. I am modelling tensile simulation. elastic and plastic part were ok (isotropic). but i dont know how to include damage model (damage for ductile materials). I need stress triaxilaity, equav plastic strain and strain rate..where i can obtain that?..hope somebody can help.  Material used is ALSi12

Post doc: Buckling in soft polymeric materials

A post-doctoral position is available in the lab of Sachin Velankar at the University of Pittsburgh to examine buckling instabilities in soft polymeric materials. The project is experimental, and therefore some past experimental experience with polymers is desirable. However this project requires a thorough understanding of elastic instabilities, and therefore a comprehensive grasp of mechanics is absolutely essential  – indeed more important than past experimental expertise.

Interested individuals should contact velankars@gmail.com. The position is for a period of 12 months.

Forensics: residual stress of fractured part

I’ll present this below without the answer, in case you want to enjoy a little brain teaser. It is a solid and experimental mechanics problem that, while not terribly practical, I found very interesting:

A part fractures cleanly in two by brittle fracture (no plasticity) under the action of residual and applied stresses. You only have the broken part in front of you, no prior information.

 What were the original residual stresses on the fracture plane?

Split Hopkinson Compression Test data analysis

I have performed some high strain rate split hopkinson
compression tests. The oscilloscope reads the incident and reflected
displacments (in input pressure bar) and transmitted displacment (in output
pressure bar) in volt. To convert displacement in volt (output voltage) to
mechanical strain (m/m), I have a difficalty. What is the relationship between
the output voltage (volt) (the reading from oscilloscope), excitation voltage (volt)
and strain gauge Gauge Factor (GF)?

Announcing Wear of Materials 2015 - Website has just gone live

20th International Conference on Wear of Materials
12-16 April 2015
The Sheraton Centre, Toronto, Canada

The 20th International Conference on Wear of Materials will focus on both the fundamental and applied aspects of wear and friction of materials at the macro-, micro-, and nano-scale. It will address the understanding of tribological phenomena; particularly the progress in recent decades and a special session will concentrate on modeling of wear.


Paper: On finding cohesive law parameters for foam-metal interfaces

A detailed report of our work on trying to find cohesive laws for interfacial fracture is attached.  I will add the experimental data after a shorter version of this report has been published.

The reason for posting this report on iMechanica is so that people who want to replicate the tests or perform similar tests know what is involved.  As we have found out, many details and potential problems faced by an experimentalist are hard to determine from the concise papers that are typically published as journal articles.

Please let me know if you have any questions.
