Abstract: Modern computers are generally equipped with multicore central processing units (CPUs). There has been a great interest to introduce a parallelized harmonic balance method to make full use of computing resources and improve ...

Abstract: It is difficult to use conventional nondestructive testing methods to detect damage, such as loosening of bolted connections, in a space frame structure due to the complexity of the structure and the nature of the possible ...

Abstract: Loosening of bolted connections in a structure can significantly reduce its loadbearing capacity. Detecting loosening of bolted connections at an early stage can prevent failure of the structure. Due to the complex geometry ...

Abstract: An accurate singularityfree formulation of a threedimensional curved Euler–Bernoulli beam with large deformations and large rotations is developed for flexible multibody dynamic analysis. Euler parameters are used to ...

Abstract: A new locking-free formulation of a three-dimensional shear-deformable beam with large deformations and large rotations is developed. The position of the centroid line of the beam is integrated from its slope that is related ...

Abstract: Parametric instability in a taut string with a periodically moving boundary, which is governed by a onedimensional wave equation with a periodically varying domain, is investigated. Parametric instability usually occurs ...

Abstract: Parametric instability in a system is caused by periodically varying coefficients in its governing differential equations. While parametric excitation of lumpedparameter systems has been extensively studied, that of ...

Abstract: A spatial discretization and substructure method is developed to accurately calculate dynamic responses of onedimensional structural systems, which consist of lengthvariant distributedparameter components, such as strings, ...

Abstract: This paper uses the methodology developed in Part I of this work to study the longitudinal, transverse, and their coupled vibrations of moving elevator cablecar systems. A suspension cable is a onedimensional lengthvariant ...

Abstract: A round elevator traveling cable is modeled using a singularity-free beam formulation. Equilibria of the traveling cable with different elevator car positions are studied. Natural frequencies and the corresponding mode ...
