Title The Optimal Design of Ultra High Performance Cementitious Composites Anti-penetration
Abstract
High-technology weapons continue to emerge nowadays. The rapid development
of different kinds of precision guided deep penetrators has made serious challenge on
protective engineerings. Ultra high performance cementitious composites (UHPCC)
have a series of excellent performance such as high strength (compressive strength of
200MPa), high ductility and high durability. The protective engineering structures
which are made of UHPCC have a significant capacity of resistance to impact,
penetration and explosion.
In this paper, ultra high performance cementitious composites are prepared and
their static compressive, tensile and flexural properties are researched. The damage of
UHPCC subjected to high speed penetration is studied. The damage and cracking of
UHPCC are restricted under penetration by optimal design of material composition.
The failure process of UHPCC subjected to penetration is simulated using nonlinear
finite element method. A new type of UHPCC is designed by experiments and
simulation.
Key words: ultra high performance cementitious composites; penetration resistance;
finite element simulation
