Hybrid experimental-numerical determination of the loading path to fracture in TRIP780 sheets subjected to multi-axial loading
… strain histories up to the onset of fracture in multi-axial experiments. In the present work, a hybrid experimental-numerical approach is taken to determine the loading path in various fracture experiments on TRIP780 steel sheets. In most mechanical experiments on sheet metal, the localization of …

Rate-Dependent Behavior of Clay
… the mechanical response of clays under multi-axial loading conditions and predicts both drained and undrained behaviors at small and large strains. Model parameter values are determined for Boston Blue Clay, London Clay and Kaolin Clay. The performance of the model in simulating the …

Development of a High Strain-Rate Constitutive Model for Sands and its Application in Finite Element Analysis of Tunnels Subjected to Blast
… The model captures the behavior of sand under multi-axial loading conditions and predicts both drained and undrained behavior at small and large strains. Perzyna’s overstress theory is incorporated in the model to simulate the viscoplastic behavior of sand under high strain rate. The model …

Development and implementation of a multi-axial real-time hybrid simulation framework
… of structural systems subjected to earthquake loading with rate-dependent behavior. To assess the response of structural components with multi-axial loading, a loading assembly with multiple parallel actuators connected to a rigid moving platform is required to impose realistic boundary …

Anisotropic ductile fracture of metal sheets : experimental investigation and constitutive modeling
… plastic deformation and ductile fracture under multi-axial loading is highly relevant to various industrial applications such as metal forming, impact failure of structures, etc. In this thesis, a comprehensive study of the plasticity and ductile fracture of anisotropic metal sheets is …

The Effect of Atmospheric Aging on a Hybrid Polymer Matrix Composites' Material Properties
… flexural performance (in both static and fatigue loading) of the composite which had been exposed to elevated temperatures for prolonged periods of time was studied. To this end, a fatigue test was developed in an attempt to simulate the multi-axial loading conditions present on transmission …

Effect of Confinement and Temperature on the Behavior of EPS Geofoam
… soil and structural loads become subjected to multi-axial loading. Effects of confining pressure on the stress-strain behavior of EPS geofoam have been investigated in previous studies. Some studies found increases in confining stress lead to corresponding decreases in both modulus and …

Multi-axial fracture behaviour of notched carbon-fibre/epoxy laminates
… and are also often subjected to complex combined multi-axial stress conditions during service. Yet their notched multi-axial fracture behaviour remains largely unexplored. This is the main contribution of the thesis. First, a novel loading fixture for applying a wide range of in-plane loading …
