PROPOSED METHOD FOR EVALUATION OF SHEAR STATE IN A PLANE
Résumé
The shear stress state in a rectangular plate can be practically obtained only on a limited area, because the plate loading is made of concentrated forces and, therefore, in the vicinity of points of load application, the stress field is strongly disturbed. But, at great distance from the force application points, a stress state closed to the ideal pure shear is generated. There are two theoretical ways in obtaining the pure shear stress state. The paper presents a proposed method for qualitative evaluating the degree of reaching pure shear state in a rectangular plate and for predicted loading case. The method considers a loaded rectangular plate with two circular holes. The finite element method analysis of the stress state is made and afterwards compared to the theoretical and experimental (photoelastic) analysis, made by the authors in previous papers. A very good agreement of the results is obtained.
