Abstract: A new formulation is given to the problem of vibration of beams or rods carrying a concentrated mass in which the Dirac δ-function is used in the differential equation to describe the effect ...

Abstract: A power viscoplastic constitutive equation was first proposed by Bodner and Partom in 1972. This specific formula has its origin in the physical phenomenon of dislocation dynamics and due to ...

Abstract: To measure vibration of a rotating disk by holographic interferometry, the double exposure of holograms must be taken at precisely coincidental positions of the disk. A technique of accomplishing ...

Abstract: The sensitivity of base‐isolated structures to wind loadings is studied. The wind velocity is decomposed into mean and random fluctuating parts. A stationary random model for the fluctuating part of wind velocity is ...

Abstract: After middle or corner column removal, multistory frames exhibit different anticollapse mechanisms, and one of the most important anticollapse mechanisms is Vierendeel action. Based on instantaneous column removal tests, ...

Abstract: There is a potential to reduce steel tonnage for construction through the use of high-strength steel reinforcement. However, the current version of the ACI 318 code limits the yield strength of reinforcement that could be ...

Abstract: To improve the performance of a reversible rotation herringbone journal bearing (Rev-HGJB), this study uses reversible elliptical grooves on a journal bearing (Rev-EGJB) and numerically analyzes ...

Abstract: It is shown that, under certain conditions, simultaneous improvement of vibration damping capacity and interlaminar fracture toughness in composite laminates can be achieved by using polymeric ...

Abstract: Previous studies on photonic crystals raise the exciting topic of phononic crystals. This paper presents the results of tunable band gaps in the acoustic waves of two-dimensional phononic crystals ...
