Crack measurement after thermal shock is usually considered as a replacement because real-time observation of experiments difficult to achieve. This paper presents an experimental approach for displaying cracking using oxygen-acetylene flame and high-speed imaging translucent ceramic. We capture the crack propagation process, calculate speed, discuss effect sample size heat flux on propagation,...

Crack development in a changing environment is the controlling factor for stability and strength of expansive soils. Expansive soils exhibit large volumetric changes with their moisture conditions that may occasionally lead to reduced bearing capacity foundation failures. This study purports model crack initiation its spatial progression relation content drying period, respectively. Volumetric ...
