G'day all

Having a metal element with a notch like crack (assume sharp one, exhibits plasticity),  what are the actual fracture mechanism (the phases the crack goes through) in the total fatigue-life. 

please comment on these scenarios:

1- crack initiation life calculated from the (S-N, e-N), then using LEFM/EPFM to determine the cycles for the crack propagation to failure...

Q/ how to find the crack length between the two phases, I mean from which stresses and at which crack length we start the crack propagation life estimation.

IUTAM Symposium on Architectured Materials Mechanics: Call for abstracts

Submitted by Francois Barthelat on

This "Architectured Materials Mechanics" IUTAM (http://iutam.org/) Symposium will take place September 17-19, 2018 in downtown Chicago, Illinois. It aims to provide a state of the art on the engineering science (design, fabrication, mechanics) of architectured materials including (but not limited to): lattice materials, metamaterials, origami, topologically interlocked materials and bioinspired materials. The list of invited speakers can be found on the symposium website:

PhD openings in ME or MSE at Missouri S&T

Submitted by Caizhi Zhou on

PhD openings are available in Dr. Caizhi Zhou's group in the Department of Mechanical Engineering or Materials Science and Engieering at Missouri University of Science and Technology (formerly University of Missouri-Rolla). Research projects may involve crystal plasticity finite element modeling or atomistic simulations. The students will receive rigorous training and interact intensively with their academic advisor. The financial support will be in the form of GRA with a monthly stipend of approximately $2100 for 12 months each year (the tuition will be waived).

Web Workshop - Intro to Simpleware for Life Sciences, Jan 17 2018

Submitted by Simpleware on

Join us for this interactive web workshop where we will demonstrate the ease of obtaining high fidelity models from medical image data using Simpleware. We will walk you through the workflow of how to build simulation-ready models for advanced analysis of anatomies, implants, medical devices, and surgical techniques.
