Abstract: The concept of domain integral used extensively for J integral has been applied in this work for the formulation of J2 integral for linear elastic bimaterial body containing a crack at the ...

Abstract: In this study, an analytical method is presented for the computation of thermal weight functions in two dimensional bi-material elastic bodies containing a crack at the interface and subjected ...

Abstract: The interface between concrete dam and rock foundation is one of the most important regions governing the strength and stability of gravity dams. Many researchers have attempted to extend the fracture mechanics approach ...

Abstract: A damage detection and assessment method has been developed in this paper using the concepts of inverse method and fracture mechanics. The objectives are to detect, locate, and quantify any damage that has occurred within ...

Abstract: A micromechanics-based model is developed to study the fatigue response of cementitious composites. Microcrack growth, which is the predominant mechanism responsible for fatigue damage, is explicitly modeled at the mesoscale. ...

Abstract: The safety of an in-service brick arch railway bridge is assessed through field testing and finite-element analysis. Different loading test train configurations have been used in the field testing. The response of the ...

Abstract: An energy approach within the framework of thermodynamics is used to model the fatigue process in plain concrete. Fatigue crack growth is an irreversible process associated with an irreversible entropy gain. A closed-form ...

Abstract: AbstractThis study presents fast Fourier transform (FFT) based spectral analysis of acoustic emission (AE) waveforms to assess damage and fractal stick-slip processes in fiber reinforced composites. Mode I fracture experiments ...
