説明

<jats:p> A combined experimental-analytical methodology is presented for accurate determina tion of the intralaminar shear modulus G<jats:sub> 12</jats:sub> of unidirectional composites using the off-axis tension test and/or the Iosipescu test. It is demonstrated that consistent values of G<jats:sub> 12</jats:sub> can be obtained with the two methods provided that: (1) specimen geometry is optimized for the off-axis test, (2) correction factors are employed to account for the shear stress nonuni formity in the test section of Iosipescu specimens. The problem of measuring the shear strength with these specimens is discussed. The 45-deg off-axis tensile coupon is recom mended for determination of the shear modulus. The 0-deg Iosipescu specimen is recom mended for determining an upper lower bound on the shear strength. </jats:p>
