Standard Test Method for Normal Impact of a Soft Projectile on a Clamped Plate
AS7372
This document describes a method for measuring deformations from a normal impact between a soft or frangible projectile and clamped plate. The document describes the hardware, setup, and instrumentation required. In this test method a soft body projectile impacts a square ductile plate clamped on all four sides. This test is intended for measuring the remaining plastic deformation of the target after the impact.The values stated in either SI units or inch-pound units are considered separate standards. The values stated in each system may not be exactly equivalent; therefore, each system must be considered as independent. This standard does not address all of the safety concerns associated with its use. It is the responsibility of each user of this standard to ensure that any safety issues are properly addressed.
Rationale: This method can be employed to generate data useful in developing and validating computational models for soft or frangible objects such as ice, soft polymers, and materials used to simulate birds for aircraft certification testing. The method can also be used to provide comparison data in the development of physical simulants for bird strike testing of aeronautical structures and bird ingestion testing of aircraft engines exposed to such risks.
