Determination of the in-plane shear modulus by the plate torsion method.\r\n\r\nThe Standard specifies a method for determining the in-plane shear modulus (G12) of fiber-reinforced plastic composite materials using a standard plate sample. When applied to isotropic materials, the measured shear modulus is independent of direction.\r\n\r\nThe method is used to determine the shear modulus of test specimens, but not to determine shear strength. It applies to a plate supported at two points on one diagonal and loaded on the other diagonal by the simultaneous movement of two point loads attached to a cross beam.\r\n\r\nThe method is suitable for use with fiber-reinforced plastic composites with thermoplastic and thermoplastic matrices.\r\n\r\nBecause shear strain is applied under bending conditions, for laminated materials with different fiber formats and\/or different orientations, the layers of material must be well distributed across the section so that they are approximately \u00abhomogeneous\u00bb in length. the thickness direction.\r\n\r\nThe principal axes of the material, if any, should be oriented perpendicular to the edges of the plate.\r\n\r\nNOTE This method can be applied to unreinforced polymers and other materials (for example, metals, ceramics, and metal- or ceramic-matrix composites).\r\n\r\nFor material made using unidirectional layers, the shear modulus obtained using a multidirectional specimen (i.e., 0\u00ba\/90\u00ba\/\u00b145\u00ba) is not the same as that obtained for unidirectional or crossover (0\u00ba\/90\u00ba) material.","link":"https:\/\/techlabsystems.com\/eng\/une\/1-2-3\/une-15310\/","name":"UNE 15310","slug":"une-15310","taxonomy":"une","parent":1707,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/une\/1842","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/une"}],"about":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/taxonomies\/une"}],"up":[{"embeddable":true,"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/une\/1707"}],"wp:post_type":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/product?une=1842"},{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/normas?une=1842"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
