Ferro cement is one of the structural materials, widely used because of its advantages of excellent behavior under flexural, and impact strength. Also it has excellent mechanical properties. A total of 6 types of panels were modeled for each grade of concrete i.e. M30, M40 and M50. The thickness of ferrocement panel considered is 20 mm and 30 mm. There are two type of fibres, Corrugated steel fibers and Hooked steel Fibers, and two types of meshes, Galvanized welded square mesh and Galvanized woven square mesh are used. High velocity impact and low velocity impact test is done on Ferro cement specimen. High velocity impact test is done by Ak-47 bullet and Parabellum bullet striking with a velocity of 300 m/s, 400 m/s, 500 m/s , 600 m/s and 700 m/s and low velocity impact test is done by dropping weight of 3.5kg from a height of 0.5m and 0.75m. All of this analysis is being performed on ANSYS Explicit Dynamics. Deformation, Equivalent Stress and Normal Stress of all the panels are evaluated and compared. It is concluded that when fibers are added in the mortar deformation due to impact loading is reduced and stress resistance of ferrocement panel is increased also when welded square mesh is used instead of woven mesh penetration depth reduces.
