- Abstract
- We present a time-dependent visco-plastic model for the calculation of the temperature field in a LEC furnace and the dislocation density within the crystal. Our thermal model is global and time-dependent in order to provide accurate solutions when the geometry is rapidly modified. From the temperature field, thermal stresses and dislocation density are calculated at any stage of growth. We use a coupled isotropic model which includes plastic deformation, thermal stress relaxation and strain hardening.
