Hello I am Nagaraju,working as mechanical design engineer. In one of my project i need to find the load induced on the component while dropping the object from 1 m height on the rigid ground floor. Component details are here: Material : Sheet Metal Length: 300 mm Width : 175 mm Height : 10 mm Drop Height: 1 m Can anyone help me to find out the max load acting on the component (after impact) and also how can i find the material thickness required to withstand that load. Please let me know if any additional information required. But i found the Max load value through the formula:a^2 = (kv1^2)/(2m) where k = stiffness of the material v = velocity after impact m = mass of the object. a = acceleration after impact. so Force induced can be F = mxgxa N. Note: I found the stiffness of the materiel through simulation. (Apply 100N force and obtain the deflection value 0.1578 mm so K can be load / deflection). Pls also check whether this approach is correct. I

Hi Nagaraju, Kinetic energy = Impact force x distance travelled after impact. Kinetic energy = 1/2 * m * v^2 Velocity = (2*g*h)^0.5 You need to know distance travelled after impact, The properties of impact surface(Restitution coefficient) decides this distance and the impact time. So, Impact force can be calculated as Kinetic energy / distance travelled after impact. Hope this helps... My advice is to perform this calculation using impact simulation.
