Abstract: Nondestructive inspection of structures by modal analysis of vibration response is reported. The dependence of natural frequencies and modal damping coefficients on deterioration in structures is examined. The magnitude ...

Abstract: An experimental study of crack closure and its effects on the vibration of a simple beam shows that both frequency and damping changes due to the crack are influenced significantly, to the point of being obscured in some ...

Abstract: With a height of 52 stories and a steel structure visible from the exterior, the New York Times Building is the third-tallest building in the city of New York. Located on 8th Avenue between 40th and 41st Streets, it was ...

Abstract: A constitutive relation is formulated for coated fabrics that exhibit both elastic and inelastic, but time‐independent, responses. The nonlinear orthotropic response is represented by an elastic portion related to yarn ...

Abstract: An analytical viscoelastic model is proposed to predict the time-dependent displacement of adhesive anchoring systems under axial tension. Using the correspondence principle, the elastic solution in Paper I has been extended ...

Abstract: An elastic solution is developed for an anchor embedded in a concrete hole and bonded to the concrete through an adhesive layer that is not necessarily thin. Both bonded and debonded conditions are considered for the ...

Abstract: The conventional transient plane source (TPS) method for thin films is used for films and adhesives with thicknesses between 50 and 200 μm. Measurements with the conventional TPS method are usually inaccurate due to thermal ...
