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 ...

Crossover from quasi-static to dense flow regime in compressed frictional granular media [PDF]

, 2013
We investigate the evolution of multi-scale mechanical properties towards the macroscopic mechanical instability in frictional granular media under multiaxial compressive loading.

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 delamination behaviour of unidirectional carbon fibre/epoxy laminates reinforced by Z-Fiber® pinnin [PDF]

, 2009
-Pin reinforced carbon-fibre epoxy laminates were tested under Mode I and Mode II conditions, both quasi-statically and in fatigue. Test procedures were adapted from existing standard or pre-standard tests. Samples containing 2% and 4% areal densities

Machine Learning in Model-free Mechanical Property Imaging: Novel Integration of Physics With the Constrained Optimization Process

Frontiers in Physics, 2021
The Autoprogressive Method (AutoP) is a fundamentally different approach to solving the inverse problem in quasi-static ultrasonic elastography (QUSE).

Shear zones in granular media: 3D Contact Dynamics simulation [PDF]

, 2007
Shear zone formation is investigated in slow 3D shear flows. We simulate the linear version of the split-bottom shear cell. It is shown that the same type of wide shear zones is achieved in the presence as well as in the absence of gravity.

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 ...

PROGRESSIVE DAMAGE ANALYSIS OF GLASS-EPOXY LAMINATED COMPOSITES UNDER STATIC TENSILE LOADING AT LOW TEMPERATURE [PDF]

مجله مدل سازی در مهندسی, 2010
Because of wide applications of composites at low temperatures, mechanical properties of glass fiber-reinforced epoxy have to be assessed at low temperatures.

X-ray microtomographic characterization and quantification of the strain rate dependent failure mechanism in cenosphere epoxy syntactic foams [PDF]

, 2016
This work investigates the failure mechanism in cenosphere epoxy syntactic foams at the quasi-static and dynamic strain rates. Split-Hopkinson pressure bar experiments are controlled to stop dynamic deformation of the foams at various strain stages.
