Merits and limitations of the drop and shock tests in evaluating the dynamic properties of plastic foams

Cushioning curves for different plastic foams were determined using drop and shock tests. It was found that at intermediate static stresses the two methods give comparable results. At low and very high static stresses however, different results were obtained. An explanation was given why the shock t...

Summary:Cushioning curves for different plastic foams were determined using drop and shock tests. It was found that at intermediate static stresses the two methods give comparable results. At low and very high static stresses however, different results were obtained. An explanation was given why the shock test is more appropriate and reliable at low and the drop test at very high static stresses.
