Summary

Abstract

PhD Thesis The study of the thermomechanical response of materials to a time‑dependent heat load is of paramount importance in the design of a variety of components widely adopted in the industry and in research laboratories. Three regimes can be identified in the thermomechanical problem, depending on the heating rate: quasi‑static, slow‑transient and quasi‑instantaneous heating. This PhD thesis focuses on the latter scenario, where the heat deposition rate is high enough to lead to the origination of stress waves, propagating from the locally-heated zone to the surrounding of the structure, and superposing with the quasi-static stress field. In the first part ...
