Abstract

Based on bi-modulus theory and experimental test, the elastic-plastic model of bending bi-modulus graphite beam is established in this paper. According to the results of material test, the graphite is demonstrated to be a bi-modulus material with the ratio of compression modulus to tension modulus being approximately 1.41. By investigating the mechanical behavior of pure bending graphite beam, the deflection law of the neutral axis towards the load and the N- curve are obtained. It shows that the experimental results are in accordance with the theoretical elastic-plastic model of the bending bi-modulus beam established in this paper, which verifies the accuracy and rationality of the theoretical model.
