Numerical modelling of sandstone uniaxial compression test using a mix-mode cohesive fracture model
A mix-mode cohesive fracture model considering tension, compression and shear material behaviour is presented, which has wide applications to geotechnical problems. The model considers both elastic and inelastic displacements. Inelastic displacement comprises fracture and plastic displacements. The norm of inelastic displacement is used to control the fracture behaviour. Meantime, a failure fun...
متن کاملBuckling of Ge nanowires under uniaxial compression
Molecular dynamics simulations are performed to investigate the buckling properties of [100]-, [110]-, [111]-, and [112]-oriented single-crystalline germanium nanowires under uniaxial compression. The effects of simulation temperature, strain rate, and wire length on the buckling behaviour are investigated. The simulation results indicate that critical load clearly decreases with increasing tem...
متن کاملBuckling and failure characteristics of slender web I-column girders under interactive compression and shear
Geometric and material nonlinear behavior of slender webs in I-column girders having stocky flanges under the action of combined lateral and axial loads is investigated. Interaction curves corresponding to the application of compressive and shear loads at buckling and ultimate stages for both web plates and column sections are plotted. In addition, the effects of flange and web slenderness rati...
متن کاملFracture modes under uniaxial compression in hydroxyapatite scaffolds fabricated by robocasting.
The fracture modes of hydroxyapatite (HA) scaffolds fabricated by direct-write assembly (robocasting) are analyzed in this work. Concentrated HA inks with suitable viscoelastic properties were developed to enable the fabrication of prototype structures consisting of a 3-D square mesh of interpenetrating rods. The fracture behavior of these model scaffolds under compressive stresses is determine...
متن کاملFailure Prediction of Stringer Stiffened Composite Panels with Impact Damage under Uniaxial Compression
The in-plane compressive behaviour of thin-skin stiffened composite panels with a stress concentrator in the form of an open hole or low velocity impact damage is examined analytically. A fracture mechanics model, developed initially to predict notched compressive strength, was applied to estimate the compression-after-impact strength of a stiffened panel; in the analysis the impact damage is r...
