Critical Areas

A necessary procedure for the evaluation of reliability and durability of supporting steel structures is an identification of critical points with the stress contractors because the critical areas are decisive with regard to location of supporting structure damage or loss of functionality. The identification of critical points can be performed by means of various methods. The full-field optical method can be found among the most often used ones. In this article there is presented an application of the transmission photoelasticimetry at the full-field stress analysis of the selected construction elements.

In this paper, we analyze the stresses around the saw teeth of differently designed circular saw structures. We select a set of critical points around the saw tooth, then we calculate the equivalent stresses of these points and the maximum or minimum stresses of the different saws under different loads and rotational speeds. The saw structure factors that we examine include the diameter of circular saw blades, the depth of the circular saw, the saw tooth rake angel, the saw tooth height and the saw tooth shape. Based on our analytical results, we propose an effective approach to reduce the stress concentration around the saw tooth and thus prevent the saw tooth fracture.

Stress Concentration Factors

A review of the Stress Concentration Factors (SCFs) obtained from normal and oblique holes in thick flat plates loaded in uniaxial tension has been conducted. The review focuses on values from the plate surface and discusses the ramifications of making a plane stress assumption.

Intersection Curves

The geometry of overlapping tubular joints, the equations of intersection curves and the coordinate of the intersection point are introduced first. The variational method for simple tubular joints is extended to the stress analysis of tubular K-joints with overlap. The computer program is compiled. The stress concentration factor and the position of the hot spot of an overlapping joint are found. For the sake of proving the feasibility of our analysis and program, the computed results are compared with experimental data of our photoelastic experiment and other experiments.
