Sažetak
In the present paper the results of numerical 3D FE analysis of concrete compact tension specimen and plain concrete beam loaded by impact are presented and discussed. To account for cracking and damage of concrete, specimens are modeled by the rate sensitive microplane model for concrete. Green- Lagrange strain tensor is used as a strain measure together with the co-rotational stress tensor. Damage and cracking phenomena are modeled within the concept of smeared cracks. In the case of plain concrete beam, the contact-impact analysis is based on the mechanical interaction between two bodies. To investigate the influence of loading rate, parametric studies are carried out. The numerical results are discussed and compared with test results known from the literature.
