This study investigates the effect of stress triaxiality on failure mechanisms an-isotropic perfect and imperfect planar FCC (Face Centred Cubic) truss lattice metamaterials. Three types imperfection have been considered in numerical modelling, namely, distorted struts, missing strut diameter variation. In order to maintain constant during simulations, a novel framework was developed overcome c...

Recent years, the geometrical Bohr-Mottelson description of the collective behaviour of atomic nuclei [1] has witnessed renewed interest. This is mainly due to the discovery of analytically solvable potentials [2], intended as an approximative description of the critical points in phase shape transitions throughout the nuclear chart. The geometrical model treats the nucleus as a vibrating and r...

Neutron diffraction measurements have been performed to determine the full residual stress tensor along the expected crack path in an austenitic stainless steel (Esshete 1250) compact tension weld specimen. A destructive slitting method was then implemented on the same specimen to measure the stress intensity factor profile associated with the residual stress field as a function of crack length...

A uniaxial high-temperature tensile test of an AA7075 aluminum alloy sheet was conducted using established induction heating system. Five different types specimens were designed to obtain the stress–strain curves at forming temperatures and strain rates so as construct modify Johnson–Cook constitutive model. The stress states numerically simulated ABAQUS finite element software, triaxiality equ...
