Abstract: A variational temperature-dependent formulation is proposed and developed for dynamical problems of thermoplasticity. The variational method is based on a Hamiltonian approach using a weak form of the mixed thermoplastic ...

Abstract: Although a complete unified theory for elasticity, plasticity, and damage does not yet exist, an approach on the basis of thermomechanical principles may be able to serve as the foundation for such a theory. With this in ...

Abstract: A theory of boundary eigensolutions is presented for boundary value problems in engineering mechanics. While the theory is quite general, the presentation here is restricted to potential problems. ...

Abstract: A general boundary element method (BEM) for the complete three-dimensional Biot consolidation theory is developed which operates directly in the time domain and requires only boundary discretization. ...

Abstract: Most recently, we have developed a novel multilevel boundary element method (MLBEM) for steady Stokes flows in irregular two-dimensional domains (Grigoriev, M.M., and Dargush, G.F., Comput. Methods. Appl. Mech. Eng...

Abstract: Although Lagrangian and Hamiltonian analytical mechanics represent perhaps the most remarkable expressions of the dynamics of a mechanical system, these approaches also come with limitations. In particular, there is inherent ...

Abstract: A computational framework is proposed as an automated design cycle for the optimal seismic design of steel frames with self-centering connections. This paper demonstrates the approach by considering steel frames retrofitted ...

Abstract: A boundary element method (BEM) is presented for the dynamic analysis of axisymmetric poroelastic media, subjected to time-harmonic excitation. The integral formulation, based on the fundamental solution of Biot's poroelastic ...

Abstract: A boundary element approach is developed for problems of hot fluid-structure interaction. The structure is idealized as a thermoelastic solid, and a time-domain, boundary-only integral formulation ...

Abstract: Thermal expansion of the part can be a significant source of dimensional and form errors in precision machining operations. This paper describes a method for calculating the thermal expansion ...
