The time-thickness variation of a film of Castor Oil was determined under conditions of high intensity-short duration loading. This was accomplished through the use of a light measurement technique and a test unit designed and constructed at the United States Naval Postgraduate School. Both the method and the test unit are discussed in detail. The cases of a film between surfaces with and without relative motion were investigated. The results, in the form of oscilloscope trace photographs, show clearly indications of both plastic and elastic behavior of the film under impact loading.
