Delamination fracture of a two-dimensional functionally graded multilayered four-point bending beam that exhibits non-linear behaviour of the material is analyzed. The fracture is studied analytically in terms of the strain energy release rate. The beam under consideration has an arbitrary number of layers. Each layer has individual thickness and material properties. A delamination crack is loc...

In the dissertation, structural Finite Element Analysis is carried out. Both linear and non linear analysis is considered for the investigation. Geometry non linearity, material non linearity and boundary non linearity also called as contact analysis is considered. All the boundary conditions, loadings, material definitions considered are real in nature. Experimental validations are considered ...

background: drug resistance is widely believed to be an increasingly serious threat to global public health. we have previously reported that short term exposure of microorganisms to diagnostic ultrasound waves could significantly alter their sensitivity to antibiotics. in our previous studies, klebsiella pneumoniae showed major differences in the sensitivity to antibiotics in exposed and non-e...

Background: A theoretical study was performed of mode II delamination in a multilayered functionally graded beam configuration with considering the material non-linearity. Methods: The fracture was analysed by the J-integral approach. Two laws (quadratic and exponential) for variation of the modulus of elasticity along the beam height were applied. The J-integral closed form non-linear analytic...
