Crack Propagation Speed in the Drying Process of Paste
We investigated crack propagation in the drying process of a thin layer of calcium carbonate (CaCO3) paste experimentally. Cracks are induced by uniform desiccation from the top surface of a layer at the approximately same water content for various drying conditions. We found that the crack speed is a nonlinear increasing function of the drying rate at the cracking time although the tensile str...
متن کاملconsequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir
there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...
Numerical Analysis of Dynamic Crack Propagation: Generation and Prediction Studies
Results of “generation” (determination of dynamic stress-intensity factor variation with time, for a specified crack-propagation history) studies, as well as “prediction” (determination of crack-propagation history for specified dynamic fracture toughness vs crack-velocity relationships) studies of dynamic crack propagation in plane-stress/strain situations are presented and discussed in detail...
متن کاملFinite Element Analysis of Crack Welding Process
The numerical simulation of the crack welding process is reported in this paper. The thermo-electro-structural coupled-field finite element analysis is adopted to investigate the welding process of crack surfaces. In the simulation, the pressure-dependent and temperature-dependent electrical contact conditions are considered. From the results, the crack surfaces can melt and weld together under...
