“…The stress concentration factor was reduced in an infinite panel having a circular hole by adding anisotropic FGIM (Functionally graded incompressible material) lining. It was analytically investigated and a comparison was made with numerical method [17,18]. N. P. Patel et al have worked on stress concentration around a polygonal cutout of complex geometry within the orthotropic infinite plate.…”

The stress concentration factor is one of the most significant factors in design engineering in the modern era with lots of objectives across the world. Stress concentration is the localization of high stresses primarily due to discontinuities within the time, abrupt changes in cross-section, and contact with stresses. This paper focuses on a problem with different discontinuities as specially holes present in a plate like isotropic, anisotropic and orthotropic etc. The different methods used by various authors to evaluate stress concentration with different related parameters, and describe the study related to the results carried out by them. Finite plate with polygonal, circular, inclined circular, and elliptical types holes has been considered one of the most important design applications in the present era. In the present work, the analysis and reviews are based on the following (a) types of discontinuities, (b) types of loading, (c) material/Composites/Plies (d) orientation of discontinuities in a finite plate. Finally, the scope of this research work is incorporated.

“…Permanent joints in the form of intersecting shells made by welding are used in equipment as fittings of various designs. It is known that any design change, for example, an abrupt transition of the thickness of the walls of the apparatus, the hole and its shape in the body of the apparatus, fittings are stress concentrators [23][24][25]. These stress concentrators, depending on the type and conditions of loading, can lead to negative consequences both for the equipment and for the personnel servicing processing installations.…”

Structural low-alloy steel grade 09G2S is used in almost all industries. This steel is known in many countries, for example: in the USA it is known as A 516-55, in Japan — SM41B, SB49. The use of this steel is due to its easy weldability by welding, increased strength and wear resistance, and a wide range of operating temperatures. These steels are suitable for the manufacture of various equipment, for example, heat exchange equipment, columns, reactors, tanks, pipe fittings, etc. It is known that such devices operate under pressure, therefore, the behavior of the welded joint with a simultaneous sharp pressure relief and temperature increase in the equipment is of particular interest. For example, in case of a fire on a sealed apparatus, the personnel will abruptly relieve the pressure in the apparatus. How will the weld behave? What can happen to this connection?
