The response of 70 sleeved concrete cylinders, impacted axially using a drop weight accelerated by gravity, is described. The contact force, skin stresses and deformational response of the impacted sleeved cylinders were all measured during the impact event. The concrete cylinders, 200mm high and approximately lOOmm in diameter, were of design strength 40N/mm². They were confined by thin walled, hollow tubes of steel (of varying thicknesses), aluminium or plastic. A group of unconfined concrete cylinders was also impacted, forming a reference series. This paper explains the rationale for the tests and gives details of the experimental work and test results.
