Creep-buckling of hexagonal honeycombs with plateau borders

摘要: The creep-buckling of hexagonal honeycombs with non-uniform cell-edge thickness is analyzed. Here, the cross-section cell edges taken to be a plateau border and solid making up assumed follow power law creep. Theoretical expressions for describing elastic buckling strength failure time onset borders are thus derived. results indicate that significantly affected by distribution in edges. Meanwhile, more likely occur when applied compressive stress close strength. However, creep-bending becomes dominant if much smaller than transition from depends on their relative density, creep parameters
