摘要:

It is shown that a separation of principal stresses with different types of experiments using computers is more valid and economical for methods based on the condition of compatibility than for those based on the conditions of equilibrium. This means that first the sum of the principal stresses is determined which combined with their differences gives their values separately. In this method several equations are used of the finite difference type and all can be solved by means of an iteration procedure in computer program form.

摘要:

This paper deals with the study of stress distribution around holes in wedges. Ling and Hsu have reported a theoretical analysis for an infinite wedge of uniform thickness and variable depth (with a circular hole), using stress functions. In the present investigation, a large number of electrical resistance strain gauges of small gauge length (3 mm) were used for obtaining the distribution of stresses in a cantilevered wedge of uniform thickness and variable depth, with a circular hole subjected to end loading. The wedge was made of perspex. The results obtained indicate a maximum stress concentration factor of 1.7 using Timoshenko's method of calculating the nominal stress in the wedge at the hole boundary (using his theory of calculating stresses in a wedge without a hole). The experiments on the cantilevered wedge indicate a lower stress‐concentration factor compared with the results obtained theoretically by Ling and Hsu for an infinite wedge. In addition to vertical loading, stress distribution with a load inclined to the vertical was also obtaine

摘要:

Holographic interferometry has been applied to the analysis of a square cantilever plate subjected to a corner load. Whole field deflections were obtained from a reconstructed hologram and compared with theoretical results. Good agreement was obtained indicating thereby the precision with which even complicated structural engineering problems can be solved using the holographic technique.
