Optimal Heating

A solution of the axisymmetric Boussinesq-type problem is derived for transient thermal stresses in a half-space under heating by using the Laplace and Hankel transforms. An analytical method is developed to predict the temperature field that satisfies the prescribed mechanical conditions. Several simple shapes of punches of arbitrary profile are considered and an expression for the total load is derived to achieve penetration. The numerical results for the temperature and the total load on the punch are shown graphically.

Transient Thermal

The paper presents a thermomechanical analysis of a circular saw with the emphasis on the influence of thermal stresses on eigenmodes. Significance of the slot’s length was also investigated. The transient thermal analysis was carried out, and based on the obtained temperature field, the modal analysis was performed accounting for both thermal and centrifugal stresses. It was found that thermal stresses have a profound influence on eigenvalues. The results clearly indicate a necessity of performing analyses of this kind in order to obtain an efficient design of the circular saw. At the end, main findings are emphasized once more.
