Paper Abstract

The optomechanical properties of poly(methyl methacrylate)(PMMA) blocks imposed to indentation pressure are investigated. The intensity of a He-Ne laser beam transmitted through the blocks is found to fade down to zero (cutoff point) in an oscillatory manner as the indentation enlarged. The indentation pressure at cutoff is independent of the specimen's thickness and length (optical path). This pressure can threfore be used to account for the specimens hardness in plastic-elastic regime.
