Physics and mechanics of beta TiMo alloys - Application to forming
The aim of this project is to investigate and model the thermo-mechanical behavior of beta-stabilized titanium alloys from room temperature up to 500°C, as a function of the chemical composition and up to rupture (cf. attached file).

Below is a message from the Secretary of the Society for Natural Philosophy. A formative influence of our field passes on.
Dear Members of the Society for Natural Philosophy.
We are sorry to be the bearers of sad news, but on Tuesday June 6th, 2017, Walter Noll passed away at his home in Pittsburgh surrounded by his wife Marilyn and two children, Victoria and Peter. He was a founding member and a past Chairman of the Society. He made major contributions to the fields of continuum mechanics and thermodynamics. There will be a memorial service at Carnegie Mellon University, which has yet to be scheduled.
Secretary,
Wladimir Neves.
Selection and thermal stability of phases are important in design of high entropy alloys (HEA). In this study, phase formations in cast AlFeCoNiCu HEA were investigated. Ab-initio molecular dynamics (AIMD) simulations were used to determine crystal structures of phases at different temperatures in equiatomic composition of AlFeCoNiCu. The AIMD results showed a possible coexistence of a face-centered cubic (fcc) phase and a bodycentered cubic (bcc) phase at the room temperature and indicated stabilization of a single fcc phase above 1070 K at the equiatomic composition of AlFeCoNiCu.
Dear All,
As FEA is one of the most popular methods for the treatment of contact problems. In that, the overall contact surface is discretized a number of segments and contact integrals are evaluated in a segment-wise manner. In 2005 Fischer and Wriggers [1] presented an integration method which avoids the need of contact surface segmentations and enables the evaluation of contact integrals directly at the slave nodes of contact bodies.

A ``small'' but interesting riddle from the basic theory of vibrations. Haven't run into it in any physics/classical mechanics text/reference.
Hello , I have a small query. I'm unable to figure out the proper boundary condition to be assigned for an all side clamped plate under uni-axial and bi-axial buckling load. The plate is assumed to be under a pre-buckling uniform stress distribution over the laminate thickness.
Professor Ares Rosakis (Caltech) and Professor Huajian Gao (Brown University) were awarded the 2016 and 2017 von Karman Medals, respectively, by Professor JS Chen (UCSD), President of the Engineering Mechanics Institute, ASCE, at its annual conference in San Diego, CA, in June, 2017.
Implementing J. Dolbow T. Belytschko MATLAB code of EFGM for CFD pronlems where more than one partial differential equations are involved such as continuity, momentum and energy equations.
Can anaybody share the MATLAB code for a heat transfer problem of EFGM method using Penalty method for implementing boundary conditions.
Thanks & regards
Sarita
