用计算机模拟技术研究了韧性金属纤维涂层的多重断裂现象。对涂膜强度等力学因素的各种组合进行了模拟实验。纤维和涂层的杨氏模量和剪切模量、纤维的屈服应力和纤维的应变硬化系数以及纤维直径和涂层厚度等几何因素。这些因素对涂层膜的断裂数和分段膜的长度作为施加的拉伸应力和涂层纤维的断裂伸长率的函数的影响被澄清。
Multiple fracture phenomenon of coating film on ductile metal fibre was studied by means of a computer simulation technique. The simulation experiments were carried out for various combinations of mechanical factors such as strength of coating film. Young's and shear moduli of fibre and coating film, yield stress of fibre and strain hardening coefficient of fibre and geometrical factors such as diameter of fibre and thickness of coating film. The effects of these factors on the number of fractures of the coating film and length of segmented film as a function of applied tensile stress and elongation to failure of coated fibre were clarified.
