A first-order shear deformation finite element model for analysis of laminated composite and the equivalent FG plates

Submitted by M. Shaat on

In this paper, the first-order shear deformation plate (FSDT) model is exploited to investigate the mechanical behavior of laminated composite and functional graded plates. Three approaches are developed to transform the laminated composite plate, with stepped material properties, to an equivalent functionally graded (FG) plate with a continuous property function across the plate thickness. Such transformations are used to determine the details of a functional graded plate equivalent to the original laminated one. In addition it may provide an easy and efficient way to investigate the behavior of multilayer composite plates, with direct and less computational efforts. A comparative study has been developed to compare the effectiveness of the three proposed transformation procedures.

Affine Development of Closed Curves in Weitzenbock Manifolds and the Burgers Vector of Dislocation Mechanics

Submitted by arash_yavari on

In the theory of dislocations, the Burgers vector is usually defined by referring to a crystal structure. Using the notion of affine development of curves on a differential manifold with a connection, we give a differential geometric definition of the Burgers vector directly in the continuum setting, without making use of an underlying crystal structure.

Post-doctoral position at the University of Texas

Submitted by Ravi-Chandar on

The Research Center for Mechanics of Solids, Structures and Materials at the University of Texas at Austin invites applications for an open position as Post-doctoral Fellow. The specific project involves the characterization of the constitutive and failure behavior of structural materials (aluminum alloys, steels, titanium alloys, metal-matrix composites, polymers and other selected materials) under quasi-static and dynamic conditions.
