✦ Synopsis

The dynamic response of anisotropic thin-walled beams to blast and harmonically time-dependent loads is investigated. The structural model incorporates transverse shear, and warping restraint and includes the anisotropy of the constituent materials. As a result of the beneficial implications played by the bending-twist elastic coupling, the circumferentially asymmetric stiffness configuration, inducing such a coupling is adopted and the pertinent system of governing equations is used to study the dynamic response. Efficient solution methodologies able to predict the response to arbitrary and harmonic time-dependent excitations are used and some of the implications played by the anisotropy of beam material, transverse shear and secondary warping are outlined.

The dynamic stability problem of thin-walled beams subjected to combined action of axial loads and end moments is studied. Each force and moment consists of a constant part and a time-dependent stochastic function. Closed form analytical solutions are obtained for simply supported boundary condition
