Jrm. D'Almeida et Sn. Monteiro, The Iosipescu test method as a method to evaluate the tensile strength of brittle materials, POLYM TEST, 18(6), 1999, pp. 407-414
Composite materials with varying toughness levels were tested using the Ios
ipescu shear test method. The failure modes were analyzed and classified in
to brittle, mixed or shear modes. It is shown that the tensile strength of
the composites showing brittle failure can be determined directly from the
load values obtained by the Iosipescu shear test. The advantages of the use
of this test method in relationship to the common tensile or flexure test
methods usually used to determine the tensile strength of brittle materials
are discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
