Abstract: For deep cylindrical cups with a large height-diameter ratio, it is difficult to be hydroformed in one stroke. Reverse deep drawing is necessary after deep drawing. Deformation optimization was ...

Abstract: A system with fractional damping and a viscoelastic term subject to narrowband noise is considered in this paper. Based on the revisit of the Lindstedt–Poincarأ© (LP) and multiple scales method, we present a new procedure ...

Abstract: In monitoring the structural health of the concrete bridge, one of the most pressing problems is crack identification. Commonly used health monitoring systems could not solve the initial diagnosis of concrete bridge structure ...

Abstract: A stochastic averaging method for quasiintegrable and resonant Hamiltonian systems subject to combined Gaussian and Poisson white noise excitations is proposed. The case of resonance with خ± resonant relations is considered. ...

Abstract: We present a novel method to solve the Bagley-Torvik equation by transforming it into ordinary differential equations (ODEs). This method is based on the equivalence between the Caputo-type fractional derivative (FD) of ...

Abstract: Equi-amplitude fatigue loading experiments on five reinforced concrete T-beams were conducted to observe the fatigue damage development. Three stages of fatigue damage were seen in the experiments. The damage rapidly ...

Abstract: We propose a method to find an approximate theoretical solution to the mean first exit time (MFET) of a one-dimensional bistable kinetic system subjected to additive Poisson white noise, by extending an earlier method used ...

Abstract: The strain-hardening behavior of metal during the uniaxial tension can be treated as the competing result of generation and annihilation of statistically stored dislocations (SSDs). Geometrically necessary dislocations ...
