【 摘 要 】

The paper reports the indentation of asemi-infinite, initially stressed elastic medium under the action of anaxisymmetric rigid punch pressing the medium normally. Th~ problem hasbeen considered within the framework of incremental deformation theoryfor neo-Hookean solids. Using the Hankel's transformation, thedistributions of incremental stress and strain have been obtained.Indentations by a flat-ended c and a conical punch have been obtained asspecial cases and these effects have been studied numerically andpresentedin the form of curves. This problem has defence applicationas many launching pads and firing machines have some neo-Hookean solidsas buffer which bear enormous impact or punch during the action of themachine.
