DESIGN CURVES FOR STRUCTURAL RESPONSE DUE TO IMPACT LOADING

A method is developed to produce a design curve for predicting the response of a given type of structure to impact loading. This curve gives the maximum strain in the structure, which may have various size and material properties, due to impacts involving different masses and velocities. An example of a simply supported beam under central impact is presented in detail. Both experimental results and numerical calculations were used in establishing the design curve. This curve implies that, for large impactor masses, the controlling parameter is the ratio of structural to impactor mass; the strain is linearly proportional to impact velocity and inversely proportional to the square root of the mass ratio.
