Abstract

Maximum load capacities of bars of different cross sections wre observed to depend - in addition to material characteristics and cross-sectional dimensions - also on length. Tests have been made on the variation of ultimate load capacity in plate specimens of rectangular cross section as a function of specimen length. Measurement results have been compared to results computed with published relationships. In the actual case, test results showed fair agreement with those from the theory Goodier and Javorik for short specimens, and with Nádai's sand-heap analogy for long specimens.
