You can implement the equations in the PDE Module in Comsol. *Group A: titanium alloy Grades 1, 2, …. The thermal stress will also exist due to inhomogeneous temperature distribution, causing inhomogeneous structure change and thermal expansion behavior. Often in thermal expansion simulations, temperature change is the only active source of stress. • Geometric Nonlinearity is now available also for the Thermal Stress and Joule Heating and Thermal Expansion interfaces. Thermal characteristics must be considered in product development, for example, in systems that include temperature control combining conduction in solids and convection in fluids. Teng, Hybrid Method Combines Transfinite Interpolation with Series Expansion to Simulate the Anti-Plane Response of a ….
