Impact on composite laminated plates: An inverse method

TL;DR: In this article, a method is developed to detect the impact force history exerted on a laminated composite plate of rectangular dimensions from the recorded strain responses, which is frequently encountered in composite laminates struck by a foreign object at low velocities.

Twelve Lectures on Structural Dynamics

TL;DR: In this paper, the analysis of the single degree-of-freedom oscillator with and without viscous damping, in the time domain: Impulse response and convolution integral, and in the frequency domain: harmonic response, dynamic amplification, quality factor.

Free vibration and stability analysis of shells by the isoparametric spline finite strip method

TL;DR: In this paper, the isoparametric spline finite strip method has been applied to the free vibration and stability analysis of shells and the convergence of the method is reviewed critically.

Dynamic response of a rotating disk submerged and confined. Influence of the axial gap

TL;DR: In this article, a simplified analytical model to analyse the dynamic response of a rotating disk submerged and confined, that has been used and validated in previous researches, is used in this case, generalised for arbitrary axial gaps disk-casing.
Journal ArticleDOI

A selective review of direct, semi-inverse and inverse eigenvalue problems for structures described by differential equations with variable coefficients

TL;DR: In this article, a selective review of boundary value problems has been presented, with emphasis on the word "selective", which gives only a taste of extensive research that has been conducted since 1759 when Leonhard Euler posed, apparently for the first time, a boundary value problem.
