FEM simulation of residual stresses and plastic deformation induced by laser peening or shot peening superficial treatment
Laser shock peening (LSP) is an innovative surface treatment technique, which has been successfully applied to improve fatigue performance of metallic components. The key beneficial characteristic after LSP treatment is the presence of compressive residual stresses beneath the treated surface of metallic materials, mechanically produced by high magnitude shock waves induced by a high-energy laser pulse. Finite element analysis method has been applied in order to predict the residual stresses and plastic deformation induced by LSP.
How to write the transfer function of mechanic systems in C language?
I have finished building the transfer function model of mechanic systems in MATLAB. But now if I am going to write the model in C language, what could I do? Any hints, fire are welcome!

how to model bones using abaqus
I am a new ABACUS user and i would like to model a shoulder bones with applying muscles forces on it. I hope if any one has an idea of applying finite element as well that will be great.
A unique feature of mechanotransduction is revealed
It is generally believed that similar to soluble ligand-induced signal transduction, mechanotransduction initiates at the local force-membrane interface (e.g., at focal adhesions) by inducing local conformational changes or unfolding of membrane-bound proteins, followed by a cascade of diffusion-based or translocation-based signaling in the cytoplasm. However, all published reports, including past studies with the reporter type of construct extended here, were limited in timescale to address this fundamental issue.
Review paper by Professor Jerry Ericksen on Cauchy-Born rule; Special issue on scale effects---freely available for a month
Xin-Lin Gao and I had the pleasure of guest-editing a special issue on "scale effects in mechanics" for the journal, Mathematics and Mechanics of Solids (editor: Professor David Steigmann , UC Berkeley).
