摘要: Abstract The main purpose of this investigation is to evaluate the effect thickness, width, aspect ratio and geometry fracture toughness specimen on resultant displacement due growth plastic zone crack. analytical part evaluates ratio, flow properties as well experimental thickness width a compact tension direction contraction zone. result that size decreases constraint yielding increases CT increases. Based other result, new procedure for determination K IC has been proposed. verified by data obtained workers. overcomes limitation ASTM E399 .
