Prediction of Saturate Concrete Elastic Modulus by Considering Pores and Microcracks
, 2010 The elastic modulus of saturate concrete is investigated in this paper. Based on micromechanics of composite materials, the elastic modulus of saturate concrete is obtained by considering the deformation of both pore and microcracks in concrete.

Embryo-damage induced nucleation of microcracks in an aluminum-alloy under impact loading
, 1995 The nucleation of microdamage under dynamic loading was investigated through planar impact experiments accomplished with a light gas gun. The microscopic observation of recovered and sectioned specimens showed that microcracks were nucleated only by ...

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement
Advanced Science, EarlyView.The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...
