The Influence of Thermomechanical Coupling on the Behaviour of Athick-Walled Metallic Tube Subjected to Internal Pressure

International Journal of Applied Mechanics and Engineering, 2018
In this study, the influence of thermomechanical coupling effect - the effect of thermal expansion due to dissipation of the energy of plastic deformation, with and without taking into account the stored energy of plastic deformation (SEPD) for the ...

Relaxation behavior of laser-peening residual stress under tensile loading investigated by X-ray and neutron diffraction

Mechanical Engineering Journal, 2014
Compressive residual stresses induced by peening techniques improve the strength properties of steels, such as fatigue and stress corrosion cracking. However, the compressive residual stress might be reduced owing to thermal and mechanical loading in ...

Microcrack fracturing of coal specimens under quasi-static combined compression-shear loading

Journal of Rock Mechanics and Geotechnical Engineering, 2020
Coal pillars are usually loaded under combined compression-shear stresses at underground coal mines. Their long-term stability is critical to the utilization of underground structures, such as underground reservoirs at coal mines.

Fatigue Damage in Notched Composite Laminates Under Tension-Tension Cyclic Loads [PDF]

, 1985
The results are given of an investigation to determine the damage states which develop in graphite epoxy laminates with center holes due to tension-tension cyclic loads, to determine the influence of stacking sequence on the initiation and interaction of

A novel experimental method to characterise the shear strength of concrete based on pre-stressed samples. A comparison with existing techniques

EPJ Web of Conferences, 2018
Mode II shear fracture process can be observed in plain-concrete structures exposed to intensive loadings such as shock, blasting or projectile-impact. It is the reason why the quasi-static and dynamic shear fracturing properties of concrete need to be ...

A stochastic flow rule for granular materials

, 2006
There have been many attempts to derive continuum models for dense granular flow, but a general theory is still lacking. Here, we start with Mohr-Coulomb plasticity for quasi-2D granular materials to calculate (average) stresses and slip planes, but we ...

On dense granular flows [PDF]

, 2003
The behaviour of dense assemblies of dry grains submitted to continuous shear deformation has been the subject of many experiments and discrete particle simulations.
