Abstract The compliance equation is used to calculate the energy release rate for angle ply laminated double cantilever composite beam specimen. Instead of the traditional approach of a beam on an elastic foundation, a second order shear thickness deformation beam theory (SSTDBT) has been considered. More >

Abstract The concepts associated with concrete crack formation and propagation is discussed in the light of fractal and probability theories. These concepts are employed to model the tortuous crack path in a highly heterogeneous medium of concrete. Fictitious Crack Model (FCM)[1] is extended to analyze plain concrete beams with such tortuous cracks. The parametric study has been carried out in order to obtain the influence of various fracture parameters on the beam response. More >

Abstract A cost and time effective inspection strategy for in-service health monitoring of composites is demonstrated using the fundamental anti-symmetric A0 Lamb mode at frequencies of 15-20 kHz. In principle, this method involves analysis of the transmitted and/or reflected wave after interacting with the test-piece boundaries or discontinuities (defects). In the present work, the applicability of the technique to composite sandwich structures is explored. More >
