The finite element analysis of a cracked plate is conducted to predict stress intensity factor under various conditions using the Abaqus
finite element software. The overall behaviour of plates is affected by presence of a through crack .By using finite element modelling
aspects of the problem twenty four different cracked plate models have been generated and analyzed by Abaqus finite element analysis
software but in this paper we will take only two cases for sample calculation .The significance of various parameters such as meshing
at the crack tip, change of element type, using different number of contours, crack length, crack locations, plate material (aluminium,
copper and steel), variation of loading condition are studied. FE models were created according to different condition and analyzed
behaviours of the cracked plate and predict the stress intensity factors.
