Dual phase steels are largely used to form automotive structural parts by deep drawing involving complex loading paths, which influence the material mechanical behavior and formability, as well subsequent service life. The aim of this paper is investigate calibration a strain path change model from an experimental database simple shear tests. enhanced Homogeneous Anisotropic Hardening (e-HAH) a...

Abstract During the forming and manufacturing of engineering materials, plasticity behavior could be evolving significantly due to complex deformation history. Therefore, this study aims characterize evolution an aluminum-magnesium alloy under simple monotonic non-monotonic loading with abrupt strain path changes. Instead focusing only on one single stress state in first-step for most studies l...

The biaxial stress and thermal expansion of multilayer doped-aluminosilicate environmental barrier coatings were measured in-situ during cooling using microfocused high-energy X-rays in transmission. Coating stresses during cooling from 1000oC were measured for as-sprayed and thermally cycled samples. In the as-sprayed state, tensile stresses as high as 75 MPa were measured in the doped-alumino...

The phase behavior of amphiphilic anisometric particles is explored using Monte Carlo simulations. The particles are composed of two incompatible laterally attached units: a spherocylinder and a spheroplatelet. A liquid crystalline phase polymorphism is obtained including biaxial nematic, (quasi long range biaxial) calamitic smectic-A, biaxial lamellar and columnar phases. The simulation result...

Nematic elastomers with a locked-in anisotropy direction exhibit semisoft elastic response characterized by a plateau in the stress-strain curve in which stress does not change with strain. We calculate the global phase diagram for a minimal model, which is equivalent to one describing a nematic in crossed electric and magnetic fields, and show that semisoft behavior is associated with a broken...

We present a systematic experimental and theoretical study of the first-order phase transition of epitaxially grown MnAs thin films under biaxial tensile stress. Our results give direct information on the dependence of the phase-transition temperature of MnAs films on the lattice parameters. We demonstrate that an increase of the lattice constant in the hexagonal plane raises the phase-transiti...

Isotropic and anisotropic out-of-plane deformations induced by thin-film residual stress on thin cubic materials are studied. By transforming the compliance tensor, an analytical expression can be derived for the biaxial stiffness modulus for all directions in any given cubic crystal plane. A modified Stoney's equation, including both isotropic and anisotropic terms, can be formulated to predic...
