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...

Accurate sheet metal simulation often requires advanced strain-path dependent material models, in order to predict the response under complex loading conditions, including monotonic, reverse and orthogonal paths. More more flexible models imply higher costs terms of parameter identification, computer implementation time, robust comparison is compromised by inconsistent predictions monotonic loa...

Fatigue crack growth is a complex process that involves interactions between many elements ranging across several length scales. This work provides an in-depth, experimental study of fatigue crack growth and the relationships between four of these elements: strain field, microstructure, crack path, and crack growth rate. Multiple data sets were acquired for fatigue crack growth in a nickel-base...

A series of biaxial High Cycle Fatigue tests at room temperature is performed to build up an extensive and well-documented database. The testing specimen is a maltese cross thinned in its centre with non homogeneous strain/stress fields. The experimental protocol uses exclusively full-field strain measurements. The strains (cyclic and residual) as well as the crack initiation detection are obta...

Does work-family conflict predict strain, does strain predict work-family conflict, or are they reciprocally related? To answer these questions, we used meta-analytic path analyses on 33 studies that had repeatedly measured work interference with family (WIF) or family interference with work (FIW) and strain. Additionally, this study sheds light on whether relationships between WIF/FIW and work...

Crystallographic texture evolution was quantified as a function of biaxial strain level and strain path for AA5754-O sheet metal in an effort to provide a physical description of grain rotation resulting from in-plane stretching. Samples were incrementally deformed to near-failure in three strain states (equibiaxial, plane strain, and uniaxial modes) with the rolling direction (RD) and transver...

The effect of strain path changes on the microstructure/crystallographic texture characteristics was studied in a 22Cr-6Ni-3Mo duplex stainless steel subjected to several deformation regimes comprising forward and reverse torsion, performed at a temperature of 1000 °C using a strain rate of 1 s. A high-resolution EBSD technique, utilising an FEI Sirion FEG SEM in conjunction with a HKL Technolo...

the present paper is devoted to a new critical state based plasticity model able to predict drained and undrained behaviour of granular material. it incorporates a bounding surface plasticity model describing in multilaminate framework to capitalize on advantages of this mathematical framework. most of the models developed using stress/strain invariants are not capable of identifying the parame...
