Numerical and experimental investigation of lateral buckling of triangular plate under tension loading

In this study the initial critical load in yoke plates is found by experimental testes. The finite element analysis is carried out in both linear and nonlinear buckling cases in ansys software. Analytical solution for buckling in case of rectangular plate is investigated and compared with finite element simulation and experimental tests. For accuracy in results¡ the simple tension test is carried out for plate for both the longitudinal and transverse tensile test specimens and full stress-strain curve of steel st52 that is obtained from experimental testes import to software for simulation. The agreement between numerical¡ analytical and experimental results is very good.
