Modelling fatigue crack growth in shape memory alloys

Submitted by Emilio Martíne… on

Dear iMechanicians, I hope that you find the below work interesting. We have developed a phase field-based computational framework for predicting fatigue crack nucleation and growth in Shape Memory Alloys. The model captures the role of transformation stresses, stress-strain hysteresis, and temperature. And this is demonstrated by computing Δε − N curves, quantifying Paris law parameters, and predicting fatigue crack growth rates in several geometries, including the fatigue failure of a 3D lattice structure. 

A slender body theory for the motion of special Cosserat filaments in Stokes flow

Submitted by Ajeet Kumar on

The motion of filament-like structures in fluid media has been a topic of interest since long. In this regard, a well known slender body theory exists wherein the fluid flow is assumed to be Stokesian while the filament is modeled as a Kirchhoff rod which can bend and twist but remains inextensible and unshearable. In this work, we relax the inextensibility and unshearability constraints on filaments, i.e., the filament is modeled as a special Cosserat rod.
