This investigation for all specimens the concrete with self-contact is used. The specimen has expanded metal sheets layers. The behavior of sheets is analyzed for specimens. For experimental method the acceleration parameter are measured with the acceleration sensor. Drop hammer test machine had been used for experimental tests. For numerical method the ABAQUS software is used. Abaqus is used for dynamic test loading and it is suitable for dynamic loading. For the specimens with two and free fixed of area are investigated on experimentally. For the specimens with thin thickness the free fixed is used. The specimens without expanded metal sheet are collapsed under impact loading. The specimens with expanded metal sheet have a strong resistance for impact loading. The displacement of the specimens without expanded metal sheet is more than of the specimens with expanded metal sheet. Expanded metal sheets are simulated in the specimens with experimentally and numerically loading.
