A physically-based constitutive model applied to AA6082 aluminium alloy at large strains, high strain rates and elevated temperatures
(Journal article; Peer reviewed, 2016)This paper presents a physically-based constitutive model applied to an AA6082 aluminium alloy subjected to large strains, high strain rates and elevated temperatures. The model accounts for thermo-elasticity, thermo-vis ... -
Assessment of yield and fracture criteria using shear and bending tests
(Journal article; Peer reviewed, 2009)This article deals with the calibration of a fracture criterion that has been implemented in a material model in LS-DYNA. The failure process in thin-walled metallic materials is complex and often due to interaction between ... -
Comparative study of deposition patterns for DED-Arc additive manufacturing of Al-4046
(Peer reviewed; Journal article, 2021)Quality assurance is one of the largest challenges to the widespread adoption of metal additive manufacturing technology. Printing pattern can significantly impact the temperature distribution during manufacturing process ... -
Constitutive modeling of a graded porous polymer based on X-ray computed tomography
(Peer reviewed; Journal article, 2020)This work focuses on the constitutive modeling of a graded porous polymer pipeline coating based on X-ray micro computed tomography (XRMCT). Previous work has revealed that finite element (FE) models generated from XRMCT ... -
Nanoscale creep behavior and its size dependency of a Zr-based bulk metallic glass manufactured by selective laser melting
(Journal article; Peer reviewed, 2022)Nanoscale creep behaviors of metallic glasses (MGs) have gathered considerable interests in recent years, owing to their distinct atomistic mechanisms of plasticity. Additive manufacturing (AM) is a burgeoning technique ... -
Synthesis of alkali-silica reaction product structurally identical to that formed in field concrete
(Peer reviewed; Journal article, 2020)Alkali-silica reaction (ASR) can cause expansion and cracking of concrete. Despite significant progress over the past 80 years, the molecular structures of the ASR products remain poorly understood. These reaction products ...
