摘要
本文通过HTPB复合固体推进剂断面层的计算机层析识别(Computerized Tomography 简称CT) 实验结果分析,并在微裂纹类型单一的假设条件下定量分析了材料内部微裂纹分布的密集程度和微裂纹面积的大小,建立了HTPB 复合固体推进剂损伤的CT 数学识别模型和方法。
Based on CT experimental results of HTPB composite solid rocket propellant and under the assumption of single type of microcrack,the concentration degree and area of internal defects are quantitatively analyzed,the mathematic model and measurement method of damage are established.
