![]() Notice that the maximum displacement is expressed in terms of the length of the simply-supported edges that are adjacent to the free edge and the values of c1 are listed in the following table.
Hence, wmax = 0.054689395931 mm The formula is valid for most commonly used metal materials that have Poission's ratios around 0.3. In fact, the Poisson's ratio has a very limited effect on the displacement and the above calculation normally gives a very good approximation for most practical cases. The coefficient c1 is calculated by the polynomial least-squares curve-fitting. |
