ABSTRACT This paper describes mathematical pretending of a selected soft projectile dissemble small scale demonstrate. The main aim of the testing program is to provide information for the calibration and verification of the numeric assumption models for soft missile impact time-history simulation. The experiments be conducted some(prenominal) with dry and fluid alter missiles. The objective of the tests with fluid filled missiles is to investigate the release speed and the droplet size of the fluid dot release in the impact. The spray release velocity and droplet size are needed as an input data for numerical simulation methods to assess the spread of the liquid in the impact. The uphold object of the testing program is to develop the numerical methods for predicting the receipt of reinforced concrete structures to impacts of soft missiles. The pre-test and post-test analyses are apply for simulating the impact load time-history and structural behavior of both the missile and the stern with the aid non-linear finite element method. INTRODUCTION The events of September 11th make emphasized the need to design protective structures for important constructions against outer impact loads, caused e.g.

by colliding vehicles, and to analyze carefully the possible consequences of such events, taking into account the existing experience and information. In the bold literature there are some fairly hygienic documented test results on the subject of deformable missiles to be used as references in developing and calibrating the finite element simulation models and assessing the obtained numerical results. However, test results for fluid filled soft projectiles are not available in the open literature. In couch to support any confidence with the simulation results, experimental, recorded data is needed for verification. The main objective of the small scale test program is to develop and calibrate finite element simulation models for reinforced concrete structures impacted by deformable missiles filled...
