Abstract: AbstractLocal strain concentrations that develop where cured-in-place pipe liners span across perforations in the wall of the cast iron host pipe have been identified as a key limit state. However,... read more here.

Abstract: Irregular reflection ofacoustic weak shockwaves (acoustic Mach numbers less than 0.01) is known as the von Neumann paradox and could not be described by the three-shock theory. In this work, nonlinear reflection regimes were studied… read more here.
