Influence of notch parameters on fracture behavior of notched component
In the present study, the influence of variation of notch parameters on the notch stress intensity factor KI is studied using CTspecimen made from steel construction. A semi-elliptical notch has been modeled and investigated and is applied to finite elements model. The specimen is subjected to a uniform uniaxial tensile loading at its two ends under perfect elastic-plastic behavior. The volume...
متن کاملVirtual Trauma of Petrous bone fracture under lateral impact : from medical images to fracture process evaluation
Materials and methods A CT-Scan of a volunteer without pathology in relation with the Petrous bone was used to build a numerical model. Using Scan2Mesh [6], a tool dedicated to the generation of a mesh from medical data, 169 slices separated by a thickness of 0.6 millimeters were processed, using an automatic detection method based on thresholding. Then an anatomist checked the detected contour...
متن کاملFracture Toughness of Wood and Wood Composites during Crack Propagation
The mode I fracture toughness as a function of crack length of medium density fiberboard (MDF), particle board (PB), and Douglas-fir (DF) were all measured using a new energy-based method. PB and MDF are examples of composites that develop fiber bridging during crack propagation, which causes their toughness to increase with crack length. Longitudinal cracks in DF also displayed fiber bridging ...
متن کاملinvestigation of fracture in v-notched brittle polymers under pure shear loading
sudden fracture is one of the major failure modes in brittle materials. plexiglass (polymethyl methacrylate) is a well known brittle polymer, widely used in various industries. many types of notches, particularly v-shaped notches, are sometimes used in the components made of plexiglass. these notches can dramatically decrease the load bearing capacity of components due to the concentration of s...
