Strain rate effect on the mechanical behaviour of a textile reinforced cement composite [PDF]

, 2010
The static tensile behaviour of Textile Reinforced Cement Composites is known and can be modeled adequately. However, using these static material properties under dynamic loadings such as impact and seismic loadings, can cause over- or underestimation of

Finite-Element Simulations of the Static Behavior and Explosive-Rupture Dynamics of 500 kV SF₆ Porcelain Hollow Bushings

Applied Sciences
We investigate the explosive-rupture behavior of porcelain hollow bushings using a representative 500 kV SF6 incident as the reference case. Finite-element simulations are performed for both the static response and the rupture process.

Back stress in dislocation creep. Part 1: Basic concepts and measuring techniques [PDF]

A theory is proposed whereby the plastic deformation of metal materials is determined by the difference between the applied stress and the back stress which characterizes the resistance of the material to plastic deformation.
