Abstract:
The tensile test is an important and widely used test to determine the mechanical properties of steel
materials. In tensile test, a specimen is pulled and specimen deformation and applied load is recorded
until its fracture to draw load-displacement curve. This work presents an experimental study of the
mechanical behavior of the ASTM A633 grade high-strength low-alloy (HSLA) steel plate specimens
with edge crack at the middle during the tensile test. Experimental analysis is used to analyze the loaddisplacement
curve, and fracture surface around the crack. Also Finite Element Method (FEM) is used to
see the J-integral curve for various crack lenghs. A633 HSLA steel plate specimens are tested in FIU
Material Laboratory using a high capacity universal testing machine with various crack lengths. Phenom
microscope is used to get the best images from the crack tip surface of the fractured samples. This paper
evaluates the effect of crack length on the load-displacement curve and also fracture behavior of steel
specimens is investigated after tensile tests. Results show that with crack length increasing, yield strength,
the ultimate tensile strength, and fracture stress show a decreasing trend. Also, fracture will occur in the
angle of principle shear stress.
