Abstract: In this paper, a new controlling method combined local postweld heat treatment (PWHT) and water jet peening (WJP) was proposed to reduce full-field residual stress of girth weld with thick wall. The finite element analysis ...

Abstract: Biotreatment is an emerging reinforcement technology. Avalanche dynamics has recently been used to analyze the fracture behavior of biotreated specimens under unconfined conditions. However, the avalanche dynamics along ...

Abstract: This study investigates the acoustic emission (AE) and physicomechanical properties of concrete under three sulfate attack conditions: continuous immersion, wetting–drying cycles, and cyclic loading coupled with wetting–drying ...

Abstract: The crushing behavior of carbonate sand, due to its porous and fragile structure, exerts a significant influence on the construction of coastal engineering. The collapse of porous material usually produces elastic wave ...
