Abstract: A novel quadrature element for performing plane stress elastoplastic analysis is introduced in this paper. Differing from the popular finite-element method, the quadrature-element method (QEM) first evaluates the integration ...

Abstract: In this paper, a damage detection strategy based on distributed strain responses measured by long-gauge fiber Bragg grating (FBG) sensors is investigated. First, the distributed strain modes of a system with multiple degrees ...

Abstract: An energy damage detection strategy through disposing strain responses has been developed. First, the strain-based energy dynamic indexes for a system with multiple degrees of freedom were derived from the frequency response ...

Abstract: Feeder-bus networks between urban rail transit systems and bus stops are inefficient in terms of the cost incurred by passengers, the time taken to reach the destination, and the number and frequency of feeder buses. To ...

Abstract: Gas-bearing capacity is an important feature in the evaluation of the different properties of shale. The calculation of adsorbed gas and free gas content is the focus of the shale gas-bearing capacity evaluation, for which ...
