and flnal failure of the medium. In this paper, crack propagation and coalescence mechanism

in rock-like materials (gypsum specimens) containing two parallel and open flaws under uniaxial compressive

loads are experimentally investigated...

for prediction of fatigue crack propagation. Minimum uncertainties and capability of using closure load are the model advantages. Generating series of a non-stationary process, effects of load history in immediate last step of crack propagation using total...

Following the line of previous work ([1] and [2]), special local damage based rupture

elements have been developed that predict the failure load in an elastic continuum and,

further, are also capable of ...

at each step of crack propagations in the dam body. The results of this study would be useful to prevent possible instability of ZAVIN and other concrete gravity dams....

electron microscopy. The results showed that cracks propagate through the PSZ matrix when there is no trace of steel. However, when cracks reach steel particles they grow around the particles and choose the interface of steel and matrix as a preferable...

Abstract: Fatigue sensitive details in aging steel girders is one of the common problems that structural engineers are facing today. The design characteristics of steel members can be enhanced significantly by epoxy bonding ...
