The modal analysis of free vibration on central crack plate was done. The finite element analysis was performed in ANSYS 18.2 program workbench. The final mesh was generated in square plate with total number of nodes and elements. The plate was cracked on the central as a percentage of its length (10-40%). four cases of crack's plates studies with different boundary conditions. The result of natural frequencies as a function of crack’s length was estimated for three modes. Finally, the prediction in cracks of stainless steel plates was done by study the various dynamic in response of structures which provide a benefit method to investigate central cracks in stainless steel plates.

INTRODUCTION Plates are one of mostly structures have been used in many industries. Crack in the plate structure causes reduction in local stiffness therefore it reduces the plates strength. Any changes in the stiffness of structure have an influence in the modal parameters, such as natural frequencies and mode shapes. The natural frequencies and mode shapes are important parameters in the design of the plates structures for dynamic loading conditions. (Biancolini et al, 2005) performed free vibration of thin orthotropic plates where natura frequencies and l mode shape were estimated. (Chen and Shen, 1993) the finite element analysis was applied on the cracked plate with verity of cracks. (M.L. Pavan et al, 2017) This finite element was performed ANSYS and the vibration characteristic of problem was calculated in different in boundary conditions. Many researchers (Refs. [5,6]) the free vibration was solved on
