DYNAMIC POLYMERIC FOAM EVALUATION TO MINIMIZE BEHIND ARMOR BLUNT TRAUMA (BABT): FROM MATERIAL CHARACTERIZATION TO SIMULATION VALIDATION

Autor: JEROME MESPOULET, HAKIM ABDULHAMID, MAËLLE PEYRATOUT, PAUL DECONINCK

Publikováno v: Proceedings of the 32nd International Symposium on Ballistics.

This paper deals with the characterization of the dynamic behavior and the damping capability of a polymeric foam that is implemented on soldiers’ chest. Split Hopkinson Pressure Bars (SHPB) experiments have been performed at strain rates ranging f

APPLICATION OF A BUILDING BLOCK APPROACH (BBA) FOR A HIGH STRENGTH STEEL TRIAXIALITY DEPENDENT STRENGTH MODEL CALIBRATION: FROM DATA COLLECTION TO MODEL VALIDATION

Autor: JÉRÔME MESPOULET, HAKIM ABDULHAMID, PAUL DECONINCK

Publikováno v: Proceedings of the 32nd International Symposium on Ballistics.

This paper details a Building Block Approach (BBA) methodology developed to fit a material model for a High Strength Steel (HSS) faced to blast/ballistic events. This model includes mesh sensitivity, strain rate influence and triaxiality effect on pl

CONCRETE CHARACTERIZATION FOR BALLISTIC THREAT

Autor: HAKIM ABDULHAMID, PAUL DECONINCK, JÉRÔME MESPOULET

Publikováno v: Proceedings of the 32nd International Symposium on Ballistics.

This ongoing study aims at building a robust approach for reliable simulation of concrete behavior under ballistic impact of Kinetic Energy Penetrator (KEP) from concrete characterization to penetration efficiency. The Holmquist-Johnson-Cook concrete

IMPACT TESTS WITH SINGLE OR MULTI IMPACTORS USING A GAS GUN TO REPRODUCE IEDS’ AND UNCOMMON THREAT

Autor: JEROME MESPOULET, HAKIM ABDULHAMID, PAUL DECONINCK

Publikováno v: Proceedings of the 32nd International Symposium on Ballistics.

This paper deals with the ability to launch single impactor, sometimes with controlled angles, or synchronized multi-fragments using guns so as to reproduce Improvised Explosive Devices (IEDS) threats. This is done for a wide range of materials from

APPLICATION OF THE BUILDING BLOCK APPROACH (BBA) FOR LIGHT WEIGHT PERSONAL ARMOUR MATERIALS CALIBRATION

Autor: JEROME MESPOULET, HAKIM ABDULHAMID, MAËLLE PEYRATOUT, PAUL DECONINCK

Publikováno v: Proceedings of the 32nd International Symposium on Ballistics.

This paper presents a lightweight armor structure calibration method. The armor consists of a stacking of two materials: a ceramic tile and a backing made of UHMWPE (Ultra High Molecular Weight Polyethylene) plate. Using a building block approach, ea
