Stat Ease - Design Expert Crack

This study employed a Central Composite Design (CCD) within Stat-Ease Design-Expert v13 to model and optimize the effect of curing temperature (A), curing time (B), and hardener ratio (C) on crack density (response) in an epoxy-based coating. ANOVA revealed that temperature × time interaction was the most significant factor (p < 0.0001). Numerical optimization predicted a crack-free surface at 65°C for 45 minutes with a 1:1.2 resin-to-hardener ratio, which was experimentally validated.

It sounds like you are looking for academic or instructional material regarding software (from Stat-Ease, now part of SAS) — specifically focused on crack propagation or fracture mechanics experiments, or perhaps on troubleshooting (“cracked” versions) of the software. stat ease design expert crack
