文摘
- •
High pulse gains cannot be applied: limits in reachable overcooling and stress.
- •
Non-thermoelectric parts are fundamental for thermal dynamics, stress calculations.
- •
Stress distributions are complex, tend to concentrate in corners at all instants.
- •
Max stresses occur at end of pulse and predominant component is the vertical.
- •
A pulse threshold variable with TE length exists so that any time can be applied.
