Distal humeral fractures are common fractures especially in immature small breed dogs. The pathogenesis is still unknown. For this study, a three- dimensional bone model of the canine elbow was created and finite element analysis performed in order to determine the relationship between fracture type and bone interactions. Fused and non-fused humeral condyles were considered. A failure criterion...

Steady-state creep response in a rotating disc made of Al-SiC particle composite having linearly varying thickness has been carried out using isotropic/anisotropic Hoffman yield criterion and results are comparedwith those using vonMises yield criterion/Hill’s criterion ignoring difference in yield stresses. The steady-state creep behavior has been described by Sherby’s creep law. The material ...

BACKGROUND Fracture risk assessment tools are useful to calculate the long term probability of osteoporotic fracture. However, how it reflects bone quality is unknown. The aim of this study was to correlate the WHO clinical fracture risk assessment tool, FRAX, with bone mechanical properties. METHODS Six patients submitted to hip replacement surgery, either due to osteoporotic fractures or to...

Vertical rolling is an important technique used to control the width of continuous casting slabs in hot-rolling field. Accurate prediction vertical force a core point maintaining rolling-mill equipment. Owing limitation algorithm use, accuracy most models based on energy method can only reach more than 10%. Therefore, it challenging optimize rolling-force model improve accuracy. An innovative a...

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...

All yield criteria that determine the onset of plastic deformation in crystalline materials must be invariant under inversion symmetry associated with a simultaneous change sign slip direction and plane normal. We demonstrate consequences this on functional form effective stress, where only lowest order terms obey are retained. A particular criterion is obtained for do not Schmid law, hereafter...
