A Comparison of Test Methods for Shear Properties of the Cores of Sandwich Constructions



ASTM C 273 and BS 4370 single block tests for shear properties of sandwich cores are critically examined. A previous appraisal using finite element modelling is highlighted and extended to include the effects of stress concentrations. Overall performance is assessed by selected laboratory programs and comparisons with panel test and flexural test methods. The ASTM method is shown to give accurate results generally. Modifications are required to the BS 4370 method. Problem areas with regard to theoretical stress concentrations in both methods are identified in relation to the test for shear strength.
