Dynamic fracture of linear medium density polyethylene under impact loading conditions
In the present study three-point-bend impact experiments were conducted using a Modified Split Hopkinson Pressure Bar (MHPB) to better understand the correlation between impact velocity and critical dynamic energy release rate at crack initiation in linear medium density polyethylene (LMDPE). The MHPB experiments were conducted at impact velocities ranging from 1 to 7 m/s. The dynamic energy re...
متن کاملEffect of Defects on Mechanical Properties of Graphene under Shear Loading Using Molecular Dynamic Simulation
Graphene sheet including single vacancy, double vacancy and Stone-Wales with armchair and zigzag structure was simulated using molecular dynamics simulation. The effect of defects on shear’s modulus, shear strength and fracture strain was investigated. Results showed that these shear properties reduce when the degrees of all kinds of defects increase. The dangling bond in SV and DV defected gr...

متن کاملMicroleakage and fracture patterns of teeth restored with different posts under dynamic loading.
STATEMENT OF PROBLEM Many studies concerned with the microleakage of endodontically treated teeth restored with posts and cores and subjected to loading can be found in the literature. However, no studies have investigated microleakage under dynamic loading with simultaneous dye penetration, which is more relevant to clinical situations. PURPOSE The purpose of this study was to compare microl...
متن کاملAnalysis of Five Parameter Viscoelastic Model Under Dynamic Loading
The purpose of this paper is to analysis the viscoelastic models under dynamic loading. A five-parameter model is chosen for study exhibits elastic, viscous, and retarded elastic response to shearing stress. The viscoelastic specimen is chosen which closely approximates the actual behavior of a polymer. The module of elasticity and viscosity coefficients are assumed to be space dependent i.e. f...
