Dynamic coupled thermoelasticity
WebDec 2, 2024 · As an application, the newly developed model is applied to a one-dimensional half-space problem which is traction free at one end; a time-dependent thermal shock is imposed at the same end to analyze transient responses of thermodynamic field variables (temperature, displacement, strain, and stress). WebSep 1, 1998 · Dynamic thermoelasticity finds applications in aerospace engineering, pulsed lasers, fast burst nuclear reactors and particle accelerators 1, 2, 3. The classical dynamic coupled thermoelasticity 4, 5 implies an infinite propagation speed for thermal signals, which is physically unacceptable.
