A finite element approximation of the thin film limit for a sharp interface bulk energy for martensitic crystals is given. The energy density models the softening of the elastic modulus controlling the low-energy path from the cubic to the tetragonal lattice, the loss of stability of the tetragonal phase at high temperatures and the loss of stability of the cubic phase at low temperatures, and ...

We present an experimental approach to discriminate hyper-elastic models describing the mechanical behavior of rubber-like materials. An evaluation of the displacement field obtained by digital image correlation allows us to evaluate the heterogeneous strain field observed during these tests. We focus on the particular case of hyper-elastic models to simulate the behavior of some rubber-like ma...

A micromechanics based analysis to predict damage initiation in compressively loaded symmetric notched multiply laminates at efevated temperature under remote biaxial loading is described. The finite element method in conjunction with the commercial code ABAQUS® is used to solve the governing system of equations. The results obtained for the predictions are compared against a set of experimenta...

The identification of damage variables and their growth with loading in two dimensions by using only full-field displacement measurements has been proposed in this study. The equilibrium gap method is used to estimate the damage field during a biaxial experiment on a sample made of a composite material. From the analysis of a sequence of measurements, a proposed form of constitutive law is test...

The aim of the present work is to contribute characterization biaxial tensile behavior commercially pure titanium, under various in-plane loading conditions at room temperature, by a non-contact digital image correlation system. Several conditions, with load ratio ranging from 4:0 0:4 and displacement rate 0.001 0.1 mm/s, are examined. It found that yield strength ultimate sample greater than u...

On the basis of the pseudopotential plane-wave(PP-PW) method and the local-density-functional theory(LDFT), this paper studies energetics, stressstrain relation, stability and ideal strength of β-SiC under various loading modes, where uniform uniaxial extension and tension, biaxial proportional extension are considered along directions [001] and [111]. The lattice constant, elastic constants an...

Collagen content and organization in developing collagenous tissues can be influenced by local tissue strains and tissue constraint. Tissue engineers aim to use these principles to create tissues with predefined collagen architectures. A full understanding of the exact underlying processes of collagen remodeling to control the final tissue architecture, however, is lacking. In particular, littl...

We present a mean field theory to describe biaxial nematic phases of side-chain liquid crystalline polymers, in which rigid side-chains (mesogens) and rigid-backbone chains favor mutually perpendicular orientations. Taking into account both excluded volume and attractive interactions between rigid rods, novel biaxial nematic phases are theoretically predicted. We calculate uniaxial and biaxial ...
