Fracture mechanics of shape memory alloys: review and perspectives
Shape memory alloys (SMAs) are intermetallic alloys displaying recoverable strains that can be an order of magnitude greater than in traditional alloys due to their capacity to undergo a thermal and/or stress-induced martensitic phase transformation. Since their discovery, the SMA industry has been dominated by products for biomedical applications with geometrically small feature sizes, especially endovascular stents.
Call for Nominations for the Eshelby Mechanics Award for Young Faculty
It is my pleasure to solicit nominations for the "Eshelby Mechanics Award for Young Faculty". This award, launched in 2012, is given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. While interdisciplinary work that bridges mechanics with physics, chemistry, biology and other disciplines is encouraged, the ideal awardee will demonstrate clear inspiration from mechanics in his/her research.
Review Article: Atomistic Aspects of Fracture
Any fracture process ultimately involves the rupture of atomic bonds. Processes at the atomic scale therefore critically influence the toughness and overall fracture behavior of materials. Atomistic simulation methods including large-scale molecular dynamics simulations with classical potentials, density functional theory calculations and advanced concurrent multiscale methods have led to new insights e.g. on the role of bond trapping, dynamic effects, crack-microstructure interactions and chemical aspects on the fracture toughness and crack propagation patterns in metals and ceramics.
Influence of anisotropic elasticity on the mechanical properties of fivefold twinned nanowires
In this paper in the Journal of the Mechanics and Physics of Solids (vol. 84, p. 358,
http://authors.elsevier.com/a/1Rk5057Zjdx-o ) we propose a
new theory for the mechanical properties of fivefold twinned nanowires.

Dear friends,
I'm working on multiscale modeling of connective soft tissues. To this end, I employed abaqus to do computational homogenization. I faced with surprising problem during my research.
Mechanical response of collagen molecule under hydrostatic compression:Mater Sci Eng C -Mater Biol Appl. 2015
Proteins like collagen are the basic building blocks of various body tissues (soft and hard). Collagen molecules find their presence in the skeletal system of the body where they bear mechanical loads from different directions, either individually or along with hydroxy-apatite crystals. Therefore, it is very important to understand the mechanical behavior of the collagen molecule which is subjected to multi-axial state of loading.

Fast nastic motion of plants and bio-inspired structures
The capability to sense and respond to external mechanical stimuli at various timescales is essential to many physiological aspects in plants, including selfprotection, intake of nutrients and reproduction. Remarkably, some plants have evolved the ability to react to mechanical stimuli within a few seconds despite a lack of muscles and nerves. The fast movements of plants in response to mechanical stimuli have long captured the curiosity of scientists and engineers, but the mechanisms behind these rapid thigmonastic movements are still not understood completely.
