Assessment of failure toughening mechanisms in continuous glass fiber thermoplastic laminates subjected to cyclic loading
(Elsevier, 2019-03-15)Tensile fatigue behaviour of glass fiber/polyamide composites, including unidirectional ([0]8, [90]8) and cross-ply ([02/902]s, [04/904]s and [904/04]s) laminates, was studied and compared to that of similar glass fiber/epoxy ... -
Assessment of the thermomechanical performance of continuous glass fiber-reinforced thermoplastic laminates
(Elsevier, 2018-05-01)The effects of temperature on the static tensile behavior of continuous E-glass/polyamide laminates were studied in order to assess the feasibility of using the material system for structural applications. Uniaxial tensile ... -
An asymmetric elastic-plastic analysis of the load-controlled rotating bending test and its application in the fatigue life estimation of wrought magnesium AZ31B
(Elsevier, 2014-07-01)Due to different deformation mechanisms arising from limited slip systems in HCP wrought magnesium alloys, their yield and hardening in tension and compression are different. Consequently, the cyclic behavior of these ... -
Asymmetric Graetz Problem: The Analytical Solution Revisited
(American Institute of Aeronautics and Astronautics, 2017-01-01)Forced-convective heat transfer from the walls of an asymmetrically heated channel to the fluid passing through in a laminar, hydrodynamically developed flow is known as the asymmetric Graetz problem. Several analytical ... -
Bimodal grain microstructure development during hot compression of a cast-homogenized Mg-Zn-Zr alloy
