Thermal storage on encapsulated phase change materials (pcm) is under consideration. The phase change (solidification/melting) process is approximated by a quasi-stationary model, which is solved together with the one-dimensional transport equation. Results are shown by the evolution of the non-dimensional outlet temperature through non-dimensional time.
Keywords: Thermal storage, latent heat, encapsulated phase change material.

Structural impact is a topic with growing importance among researchers, engineers, industry and regulator bodies. Basic concepts of the phenomenon of impact and the analysis underlying it are introduced in this article, including the influence of the strain rate on the flow stress. The paper finishes with a discussion on various aspects of impact, including joint failure.
Keywords: impact, joint failure.
