New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures [PDF]

, 2017
The behavior of reinforced concrete (RC) structures under severe demands, as strong ground motions, is highly complex; this is mainly due to joint operation of concrete and steel, with several coupled failure modes.

Experimental study on failure characteristics and rheological properties of pillar-like rock samples with different shapes

Scientific Reports, 2023
The stability of coal pillar is extremely important to the control of rock strata movement and surface subsidence. It is of great significance for mining design to analyze the stability and failure characteristics of coal and rock pillars left after ...

Study on Deterioration Characteristics of Uniaxial Compression Performance and Microstructure Changes of Red-Bed Mudstone during Gaseous Water Sorption

Buildings, 2022
Previously conducted studies have established that gaseous water sorption of mudstone is widespread in nature. The deterioration of its uniaxial compression properties during gaseous water sorption can cause engineering problems. However, related studies

Strain Hardening of Polymer Glasses: Entanglements, Energetics, and Plasticity [PDF]

, 2008
Simulations are used to examine the microscopic origins of strain hardening in polymer glasses. While stress-strain curves for a wide range of temperature can be fit to the functional form predicted by entropic network models, many other results are ...

Birefringence Properties of Uniaxially Compressed K2SO4 crystal

Ukrainian Journal of Physics, 2013
The influence of the uniaxial mechanical pressure om < 200 bar on the temperature dependence of the birefringence Δni in K2SO4 crystals in an interval of 300–1000 K has been studied. The uniaxial pressure was found to affect only the magnitude but not the behavior of dΔni=dT.

A comparison of limited-stretch models of rubber elasticity [PDF]

, 2014
In this paper we describe various limited-stretch models of non-linear rubber elasticity, each dependent on only the first invariant of the left Cauchy-Green strain tensor and having only two independent material constants.
