Abstract null null The aim of this work is to conduct a comprehensive examination of the anisotropic plastic behavior of a sheet of commercial Zn-Cu-Ti alloy, undergoing different quasi-static deformation paths at room temperature. Various mechanical tests are performed, including uniaxial and bi-axial tensile tests, Meuwissen and shear tests, obtaining homogeneous and heterogeneous strain fields. It was observed that under monotonic loading, the material behavior, i.e. stress evolution and duct...

Abstract null null We study the electromechanical and piezotronic behaviors of a composite piezoelectric semiconductor cylindrical shell (CPCS), which consists of a piezoelectric dielectric layer and a non-piezoelectric semiconductor layer, under a uniform temperature loading. A simplified one-dimensional (1D) multi-field coupling model for the CPCS structure is established. The analysis of the tuning effect of the thermal loading as well as the effects of the geometrical parameters and the mech...

Abstract null null Increasing the fibre tensile strength is well-known to improve the ballistic performance of ultra-high molecular weight polyethylene (UHMWPE) fibre composite beams. Here we investigate modifying ply microstructure as an alternate way to enhance ballistic performance. Specifically, we numerically investigate the mechanisms via which failure is initiated in null null null null null null [ null null 0 null o null null / null null 90 null o null null ] null null n null null null n...

Abstract null null We propose the design of a novel three-dimensional porous continuous solid exhibiting negative Poisson’s ratio. The shape and periodic distribution of the pores guarantee cubic symmetry, and the directional dependence of the Poisson’s ratio and Young’s modulus shows a moderate degree of anisotropy and multidirectional auxeticity. We demonstrate the auxeticity of the porous solid numerically, solving both a periodic analysis on a unit cell and a boundary value problem on a fini...

Abstract null null This study assesses the applicability of the Weibull stress for the assessment of the crack-tip plastic constraint effect as well as the mixed mode I and II loading effect on brittle fracture resistance of a ferritic steel. Brittle fracture toughness under different crack-tip plastic constraint conditions and different loading mode conditions was respectively obtained by conducting 3-point bend (3 PB) test for single edge cracked specimens with different crack depth subjected ...

Abstract null null Physics-based crystal plasticity models rely on certain statistical assumptions about the collective behavior of dislocation populations on one slip system and their interactions with the dislocations on the other slip systems. One main advantage of using such physics-based constitutive dislocation models in crystal plasticity kinematic frameworks is their suitability for predicting the mechanical behavior of polycrystals over a wide range of deformation temperatures and strai...

Abstract null null In the context of classical interface elasticity theory, the existence and uniqueness of elliptical neutral inhomogeneities in an isotropic plane have been verified in the literature for plane deformation when the interface effects are described by variable interface parameters and the matrix is subjected to a uniform external loading. In this paper, we examine similar existence and uniqueness of neutral inhomogeneities in an anisotropic plane under the same conditions. We sho...

Abstract null null The worldwide growing demand for additive manufacturing (AM) has led to the development of wire and arc additive manufacturing (WAAM) technique. In this work, SS316L and ER70S6 thick-walled cylinders were produced, and specimens were extracted in the as fabricated condition. For comparison, bulk SS316L and AISI 1020 specimens were machined from cold drawn (also in as received condition) bars and tested accordingly. Four types of specimens were used: “dog-bone” for tension, cyl...

Abstract null null The design of high-strength and high-toughness materials that can sustain high shock-wave loadings is crucial for both armor and civil applications. We propose a bioinspired diamond composite that mimics the brick-and-mortar arrangement of nacre from mollusk shells and evaluate its performance for different diamond brick contents using lattice-spring model. In this work, we present a systematic investigation elucidating the effects of volume fraction of diamond brick, on the s...

Abstract null null The objective of this paper is to use quantitative thermography for fatigue damage assessment and life prediction of welded components. The energy dissipation during fatigue process is taken as an effective index of fatigue damage to develop a nonlinear damage accumulation model, and the model is extended to evaluate the fatigue damage and residual life of the specimen subjected to variable loading. Experiments are performed to validate its applicability, and the relationships...
