Real-Time Ballistic Impact Deformation and Strain Measurements of Transparent TROGAMID Polyamides

Abstract

Dynamic deformation of two transparent TROGAMID polyamide materials upon ballistic impact is analyzed by utilizing a photogrammetric technique known as digital imaging correlation. The extent of out-of-plane deformation and shear deformation is greater in TROGAMID CX-7323 than in TROGAMID T-5000. These real-time, full-field deformation measurements at various impact velocities enable the differentiation and validation of mode of failure, which is not obtainable directly from the MIL-SPEC V(50) measurements, between the two select polyamide materials. TROGAMID CX-7323 is more ductile than TROGAMID T-5000, despite their similar V(50) values.
