A study of dynamic thermal expansion using a laser-generated ultrasound one-dimensional model

Abstract

International audienceThe laser-ultrasound 1D model is used to describe phenomenologically the behavior of a non-conductive infinite plate subjected to different types of temperature raises: uniform (in z) and instantaneous (in t), uniform and non-instantaneous, non-uniform (exponential) and instantaneous. We show that this simple model can be used to understand the basics of dynamic thermal expansion
