This app presents stress intensity factors of cracks K. The stress intensity factor of a crack represents the intensity of crack tip stress distribution. There are three different crack opening modes: mode I tension; mode II in-plane shear; mode III out-of-plane shear.
The K concept is of special value for studies of fatigue cracking in metallic structures. In the use of fracture mechanics, estimates of K for potential or real cracks are commonly needed.
• This app determines the geometry factor and stress intensity factor for a given configuration and crack length.
• Central and edge cracks.
• Cracks at holes and notches.
• Cracks in cylindrical and spherical shells.
• Metric or Imperial units may be used.
• The equations used are displayed in a PDF file.
• The results may be shared using an email option.
