Finite Element Modeling (Fem) For Evaluation Of Stress Intensity Factor For A Crack At An Angle And For V-Notch Specimen
The finite element modeling (FEM) for evaluation of stress intensity factor for a ‘crack at an angle’ and for ‘v-
notch specimen’ has been investigated in this study, FE modeling is performed through which the behavior of the material is
understood at different loads and at different crack length of the specimen. Here stress intensity factor KI and the stress
intensity factor KII are determined. The theoretical and ANSYS values are compared with the target solution provided in the
NEFMS benchmark problems. The stress intensity factor elegantly the crack characterizer and for mode one, two, three, the
stress intensity factor is expressed as KI, KII, and KIII investigation is closer to the crack tip, often implies minute details to
understand how elastic materials deform and dislocation behavior. This paper work emphasizes the study of stress intensity
factor of ‘crack at an angle’, of a specimen in various loading conditions for different ‘crack angles’ and similarly the study
of stress intensity factor for ‘v-notch’ of a specimen in various loading condition under different ‘crack length’ using the
target solution is performed.
