TL;DR: In this article, the instability of composite laminated plates under uniaxial, harmonically-varying, in-plane loads is investigated, both symmetric cross-ply and antisymmetric angle-ply laminates are analyzed.

TL;DR: In this paper, a deformed, slender beam attached to a vertically oscillating base is used in a vibration isolation application to reduce the motion of a supported mass, which is modeled as an elastica and solved numerically using a shooting method.

TL;DR: In this paper, the structural response of structural elements to a simple harmonic, transverse excitation is considered, and the effects of both initial curvature and midsurface stretching are included; thus, the governing equations contain both quadratic and cubic terms.

TL;DR: In this paper, the effects of failure of one or more cables or hangers (suspenders) on suspension bridges are analyzed, where a harmonic vertical force and an aerodynamic moment proportional to angular velocity are applied to the deck.

TL;DR: In this article, a uniform formulation of sensitivity analysis for beams and plates is presented in terms of generalized stresses and strains, and optimal design problems for stress and deflection constraints are formulated and the relevant optimality conditions are derived using the concept of a linear adjoint structure.
