Computer Simulation of Normal and Oblique Impacts of Yawed Projectiles on Ceramic Targets
The investigation of three-dimensional problem of normal and oblique interaction of yawed pro jectiles with ceramic plates in a velocity range up to 4000 m/s was carried out by the finite element method. The paper presents an advanced constitutive model of AD995 Alumina. The model of a damaged mediu...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The investigation of three-dimensional problem of normal and oblique interaction of yawed pro jectiles with ceramic plates in a velocity range up to 4000 m/s was carried out by the finite element method. The paper presents an advanced constitutive model of AD995 Alumina. The model of a damaged medium is used; it is characterized by a possibility of crack initiation and propagation under impact loading. A kinetic fracture model of the active type developed earlier for the simulation of fracture in various materials is used for numerical modeling of ceramic failure at high velocity impact. Temperature effects are taken into account in the constitutive model. |
