Abstract
⺠Micro-scale deformation and fracture of gypsum under Vickers loading was examined. ⺠At lower loads: dislocation saturation and localized necking was observed. ⺠Load increase: increase in subsurface cracking and surface smoothness. ⺠Smoothness related to plastic flow of water-reduced gypsum (Raman measurement). ⺠Voids left by evaporated water (118-142 °C) enable gypsum to deform more easily.
