一、前言寻求一些有效的轻质结构,一直是人们不断追求的目标。等网格结构就是一种很有前途的结构。它是一个连续的加劲等网格。由重复的等边三角形肋构成。这种等边三角形网格从宏观上看具有各向同性性能。因为它是一个加劲概念,因而主要应用在抗屈曲结构中。抗弯刚度主要是由等网格肋提供的,对于肋的任何损伤都将减少结构的抗屈曲能力,但是由于它 I. Foreword The search for some effective lightweight structures has always been the goal pursued by people. Grid structure is a very promising structure. It is a continuous stiffened grid. Consists of equilateral triangular ribs. This equilateral triangle mesh has isotropic behavior at a macroscopic level. Because it is a stiffening concept, it is mainly used in anti-buckling structures. Bending stiffness is mainly provided by iso-grid ribs, and any damage to the ribs will reduce the buckling resistance of the structure, but since it
