i want to know the material grade which is used in APPLE phones/laptop circuit chassis 

i know that aluminium is used .grade please????

Recent experiments showed that the Lode parameter, which distinguishes between axisymmetric and shear dominated stress states, has a profound effect on material ductility, especially at low stress triaxiality. Consequently, the theoretical framework for void growth and coalescence is currently being revisited, which often involve performing representative volume element (RVE) calculations. The present study investigates an RVE composed of a cubic unit cell containing a spherical void at its center.

3D numerical simulations of fatigue damage of multiscale fiber reinforced polymer composites with secondary nanoclay´reinforcement are carried out. Macro–micro FE models of the multiscale composites are generated automatically using Python based software. The effect of the nanoclay reinforcement (localized in the fiber/matrix interface (fiber sizing) and distributed throughout the matrix) on the crack path, damage mechanisms and fatigue behavior is investigated in numerical experiments.

The Department of Civil and Environmental Engineering at the George Washington University invites applications for a tenure-track faculty position at the level of Assistant Professor starting fall semester 2015. The primary field of interest is mechanics of geomechanical and structural systems. Applications from women and under-represented minority groups are strongly encouraged.

Hi all,

We've recently published a paper on

Micromechanical Study of the Interface Properties in Concrete Repair Systems

It deals with nanoindentation and numerical simulation of the interface zone in concrete repair systems.
