In this paper, mechanical buckling analysis of composite annular sector plates with bean shape cut out is studied. Composite material sector plate made of Glass-Epoxy and Graphite-Epoxy with eight layers with same thickness but different fiber angles for each layer. Mechanical loading to form of uniform pressure loading in radial, environmental and biaxial directions is assumed. The method used...

Order parameters and phenomenological theory for both high- and low-symmetry biaxial nematic phases are presented and it is predicted that the chiral low-symmetry biaxial phase must be ferroelectric. This conclusion is based on general symmetry arguments and on the results of the Landau-de Gennes theory. The microscopic mechanism of the ferroelectric ordering in this chiral biaxial phase is ill...

The Lüders plateau behaviour is a phenomenon of stress discontinuity associated with strain localisation which can affect the fracture mild steel subjected to plastic strains. Together experimental studies biaxial loading tests digital image correlation (DIC), this work considers effect on mechanical L450 loading, using so-called “up-down-up” (UDU) constitutive model in finite element analyses ...

• The accuracy of two fatigue criteria for multiaxial random loading is discussed. Fatigue tests related to 10NHAP steel and available in the literature are simulated. lifetime crack initiation path estimated through present criteria. agreement between experimental data theoretical results satisfactory. compared with those determined three In paper, capability both estimating life predicting me...
