Abstract

Experimental values of the strength and deformation are presented for SO-95, SO-120, and SO-140 acrylic plastics (polymethyl methacrylate: plasticized, unplasticized, and copolymer) stressed in unaxial tension at v=10 mm/min, stationary temperature gradients of from 2.5 to 17.5 deg/mm over the thickness of the material, and a constant cold-face temperature of 25°C. The deformation properties under these conditions are described: in the presence of a temperature gradient the ultimate strains are higher than for a uniform temperature field at a temperature equal to the cold-face temperature, and the elongation at break falls as the hot-face temperature rises. The tensile strength of plastics with a temperature drop over the cross section can be approximately calculated from the mechanical characteristics obtained for a uniform temperature field.
