Abstract
An in-situ apparatus is provided for monitoring the state of stress/strain and cracking in a die surface. The apparatus may also be used to facilitate the prudent removal of the die from the surface so that it may be repaired before catastrophic failure occurs. Accordingly, the yield of a process used to generate die cast structures may be greatly increased.
