✦ Synopsis

A recently developed tensile test specimen geometry has been used to evaluate the tensile characteristics of plain and FRC. Previous experimental results have indicated some significant dependency of geometry on the specimen failure and have indicated discrepancies between the results obtained using this new direct tension geometry and previous flexural tension geometries. The present paper considers the results of an intial numerical study undertaken to investigate this phenomenon. The preliminary results indicate that the tensile stress distribution, obtained in the new geometry, is significantly non uniform and that the degree of non uniformity is dependant on the specimen geometry. The result of the numerical study offer an explanation of the variation in the experimental results.
