Dear Colleagues,

Our paper on elastic instabilities in soft fiber composites recently got published in International Journal of Engineering Science. In this paper, we explore how the stiffening behavior of composites phases influences the development of instabilities and associated buckling patterns. To do that, we use non-Gaussian hyperleastic  model to define the constitutive behavior of phases. 

A finite element formulation is presented for a direct approach to model elastoplastic deformation in slender bodies using the special Cosserat rod theory. The direct theory has additional plastic strain and hardening variables, which are functions of just the rod's arc-length, to account for plastic deformation of the rod. Furthermore, the theory assumes the existence of an effective yield function in terms of stress resultants, i.e., force and moment in the cross-section and cross-section averaged hardening parameters.

Dear All

I hope you are doing well and staying healthy.

Dear Colleagues,

We are organizing a focus session on "02.01.15 Physics of Bio-Inspired Materials (DSOFT, DBIO, DPOLY) [same as 04.01.42, 01.01.54]" for the 2021 American Physical Society Meeting (March 15-19), which will be an online meeting. This session covers most of the classical and emerging research topics of bio-inspired materials.

Dual-phase nanostructuring as a route to high-strength magnesium alloys, Wu, Chan, Zhu, Sun, Lu, Science, 2017

Novelty/impact/significance:

The IRDS analytics lab (https://alouhghalam.sites.umassd.edu) at the University of Massachusetts Dartmouth (UMassD) has a fully-funded PhD position. The graduate student will be working on an exciting project related to the dynamics of locally resonant structures and machine learning techniques with application to source localization. This position will involve working closely with a multidisciplinary team from UMassD, UMass Lowell and NUWC.

Heterogeneous lamella structure unites ultrafine-grain strength with coarse-grain ductility, Wu, Yang, Yuan, Wu Wei, Huang, Zhu, PNAS, 2015

Novelty/impact/significance:

A novel heterogeneous lamella structure in Ti is created, which is as strong as the ultrafine-grained Ti and simultaneously as ductile as the coarse-grained Ti, with higher strain hardening than the coarse-grained Ti.
