Penetration of Projectiles into Seafloor Soils

Abstract

This report presents Laboratory model tests and field tests of a study conducted on projectile penetration into seafloor soils. Existing relationships for predicting penetration behavior are considered, and new relationships are developed to account for observed test results. The derived relationships incorporate conventional soil engineering properties with special modifications to account for the effects of velocity, penetrator shape, and penetration depth on penetration resistance. These relationships are shown to compare favorably with previously available methods for predicting penetration depths where soil properties are known. Recommendations are presented for the evaluation of constants in the relationships. A calculation procedure is presented for solving the penetrator equations of motion by hand or with the aid of a small computer. An example problem is solved by hand to illustrate the use of the proposed relationships in the calculation procedure. Recommendations are made for use of results in preliminary and detailed engineering work.
