摘要: Abstract The creep-rupturing of regular hexagonal honeycombs with dual imperfections variable-thickness and non-straight cell edges is theoretically analyzed. taken to be a Plateau border the profile circular. At same time, solid making up in assumed obey power law creep while its rupturing follow Monkman–Grant relationship. Theoretical results indicate that affected by distribution edges, curvature parameters edges. In addition, effects on strain rates times are more drastic than those any single imperfection. Furthermore, it verified normalized approximately equal products each
