fracture toughness evaluation for brittle polymers under combined tensile-shear loading

fast fracture is one of the major failure modes in brittle polymers. generally, crack growth in these polymers may occur under combined tensile-shear loading. however, the fracture test data reported previously for some dental restorative resins can not be predicted by using the available fracture criteria.in this paper, a modified fracture criterion is used for estimating the fracture load for...

Dynamic fracture initiation in brittle materials under combined mode I/II loading

A new test method has been developed to measure the resistance of dynamic fracture initiation in brittle materials under combined mode I/I loadings. The Brazilian disks with center-cracks have been fractured under oblique impact loadings in diarnetral-compression. The dynamic stress intensity factors of mode I and H are evaluated from the superposition integrals of the step response functions f...

A Laboratory Investigation of Acoustic Emissions Associated with the Brittle Fracture of Rock Under Dry and Wet Conditions

We have carried out a series of laboratory experiments on AE monitoring to investigate the fracture behaviour of some dry and water-saturated rock samples of south-east Gujarat and Maharashtra which have been experiencing prolific seismicity in recent years in India. The results obtained from the study of Pavgadh rhyolites and Godhra granites tested to failure under triaxial compression are pre...

Three-Dimensional Finite Element Analysis of Tensile-Shear Spot-Welded Joints in Tensile and Compressive Loading Conditions

Выполнен трехмерный конечноэлементный анализ образцов с одним, тремя и пятью точеч­ ными сварными швами при растяж ении и сжатии. Д ля расчета на прочность исполь­ зуется распределение упругопластических напряжений в корне точечного шва. Предложена методика субмоделирования, позволяющая получить более точные результаты конечно­ элементного расчета точечных швов малых размеров. Схема численного ...

investigation 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...
