Fuzzy Dynamic Characteristic of Concrete Material under Impact Loads

摘要

For different impact velocity (high, middle and low), the concrete material shows different characteristics. To describe such a characteristic effectively, the concept of fuzzy dynamic characteristic of concrete material is presented. Based on this concept, a fuzzy model to predict the penetration is given and a total penetration process of a projectile against semi-infinite concrete target is analyzed and calculated. From the comparison with the tests, the good agreement is obtained.
