In this study, the feasibility of using Lamb waves in functionally graded (FG) nano copper layered wafers nondestructive evaluation is evaluated. The elastic parameters and mass densities these vary with thickness due to variation grain size. power series technique used solve governing equations variable coefficients. To analyze multilayered structures, which material are continuous but underiv...

this paper deals with local buckling analysis of rectangular functionally graded material plates using finite strip method and based on classical plate theory. the modulus of elasticity of the plate is assumed to vary according to a power-law distribution in terms of the volume fractions of the constituents. the principle of minimum total potential energy is employed to obtain stiffness and sta...

In this paper, we extend the LASSO method (Tibshirani 1996) for simultaneously fitting a regression model and identifying important interaction terms. Unlike most of the existing variable selection methods, our method automatically enforces the heredity constraint, that is, an interaction term can be included in the model only if the corresponding main terms are also included in the model. Furt...

An alternative Skolemization method, which removes strong quantifiers from formulas, is presented that is sound and complete with respect to intermediate predicate logics with the finite model property. For logics without constant domains the method makes use of an existence predicate, while for logics with constant domains no additional predicate is necessary. In both cases an analogue of Hebr...

Electrorheological (ER) materials are suspensions of micron sized particles in insulating, dielectric fluids. The mechanical properties of these materials can be controlled by regulating an electric field through them. Variable properties include stiffness, damping, and yielding behavior. At high electric fields, material property changes are rapid and immediately reversible. ER technology has ...
