Various aspects of the tetragonal ( t ) to monoclinic m transformation during degradation have been studied experimentally and theoretically in yttria‐stabilized zirconia polycrystals (Y‐TZP), i.e., polycrystalline ‐ZrO 2 containing Y O 3 solution. Transmission electron microscopy (TEM) revealed that protruding grains at surface Y‐TZP specimens do not transform under corrosive conditions (250°C, humid atmosphere) even after an annealing time 168 h. Eigenstresses due anistropic thermal...
The elastic behaviour of a bimaterial interface with interfacial cracks, misfit dislocations and thermal stresses can be described in simple manner by using the com posite parameters α β, effective modulus elasticity E*, assuming plane deformation ideally bonded isotropic materials. A coefficient K T for thermally duced stress intensity at serves as measure mechanical compatibility two An examination these many composite materials shows that values β are limited to nar row range material...
ABSTRACT The influence of welding residual stresses in stiffened panels on effective stress intensity factor (SIF) values and fatigue crack growth rate is studied this paper. Interpretation relevant effects different length scales such as dislocation appearance microstructural nucleation propagation taken into account using molecular dynamics simulations well a Tanaka–Mura approach for the analysis problem. Mode I SIFs, K , were calculated by finite element method shell elements tip...
Friction and wear tests were performed on AISI 1045 steel specimens with different initial roughness parameters, machined by a creep-feed dry grinding process, to study the friction behavior pin-on-disc tester in sliding conditions. Average surface (Ra), root mean square (Rq), skewness (Rsk) kurtosis (Rku) involved order analyse influence of behavior. The observations reveal that parameters higher Ra, Rq Rku will lead longer initial-steady transition period tests. plastic deformation mainly...
A new empirical interatomic potential of the embedded atom type is developed for Fe-Cu system. The alloy system was constructed to reproduce known physical parameters alloy, such as heat solution Cu in Fe and binding energy a vacancy matrix. also reproduces first-principle calculations properties metastable phases This atomic interaction model used simulation studies interface small coherent precipitates dislocation core structure. phase stability body-centred cubic analysed.
