The bending behavior of composites sandwich plates with multi-layered laminated face sheets has been investigated, using a new four-nodded rectangular finite element formulation based on a layer-wise theory. Both, first order and higher-order shear deformation; theories are used in order to model the face sheets and the core, respectively. Unlike any other layer-wise theory, the number of degre...

in fruit trees damage of frost and freezing is depended to time of chillhng and tree phonological stage. almond (prunus amygdalus b. (and apricot (p. armeniaca l.) cultivars are usually the first fruit trees to bloom and susceptible to damaging frosts in the early spring. a study was conducted on different types of almond and apricot cultivars in order to investigation the main factors related ...
