Dynamic Instability Analysis of Transverse Vibrations of Functionally Graded Rectangular Plates under Moving Masses

In this paper, dynamic instability due to parametric and external resonances of moderately thick functionally graded rectangular plates, under successive moving masses, is examined. Plate mass per unit volume and Young’s modulus are assumed to vary continuously through the thickness of the plate and obey a power-law distribution of the volume fraction of the constituent. The considered rectangu...

Non-linear Dynamic Analysis of Steel Hollow I-core Sandwich Panel under Air Blast Loading

In this paper, the non-linear dynamic response of novel steel sandwich panel with hollow I-core subjected to blast loading was studied. Special emphasis is placed on the evaluation of midpoint displacements and energy dissipation of the models. Several parameters such as boundary conditions, strain rate, mesh dependency and asymmetrical loading are considered in this study. The material and geo...

Free linear vibrations of cables under thermal stress

This paper aims at investigating the effect of thermal stress on free linear vibrations of cables. An analytical model extending Irvine’s theory to thermoelasticity is proposed. In addition to the sag-extensibility parameter, this model yields a second dimensionless independent parameter related to the temperature change. Some general two-dimensional contour plots are presented giving the relat...
