Shear values at 0° to the fibers obtained by the Johnson shear and block-shear methods showed relatively good agreement. This equation implies that the undrained shear strength of soil should be 1.7 kPa at the liquid limit and 170 kPa at the plastic limit. Abrasion Testing The shear strength of a plastic is the maximum load required to shear a specimen in such a manner that the resulting pieces are completely clear of each other. ). Set alert. The arrows indicate the measured plastic strains which are compared to those implied by the circular von Mises plastic potential. Plastic shear strength of continuous reinforced beams Colin Gurley TAFENSW Sydney Institute, Australia. The force per unit area (MPa or psi) required to break a material in such a manner is the ultimate tensile strength or tensile strength at break. Moreover, the fact that the shear strength is calculated by dividing the load by the area of the shear strength is calculated by dividing the load by the area of the sheared edge (circumference X thickness) should not be interpreted as indicating that the shear strength value so obtained is solely a material property, independent of thickness. Based on the shear and tensile tests, A shear strength estimate would typically be made under the presumption that the ratio of shear strength to tensile strength would be similar to the ratio between shear modulus and tensile modulus, and utilize the Poisson's ratio (which typically remains constant regardless of cross-linking or chain length). The shear strength is then readily determined as half the unconfined compressive strength of undisturbed samples. ASTM D 732, first published in 1943 (Reference 1), defines a punch-type of shear test. Several methods were employed to evaluate the shear strength of plastic laminate panels 1/8 inch in thickness and reinforced with unwoven glass fibers. However shear values are greater than unreinforced soil. Layered composites’ shear strength is determined by testing the limits of its laminates, layers and fibres [5]. For chemically resistant plastic, view our Chemical Resistance of Plastics chart. For example, tensile properties of plastics such as plastic tensile strength and rigidity can be determined according to DIN EN ISO 527 by briefly applying load in one direction with a tensile test.
