摘要: AbstractA three-dimensional internally pressurized frame-membrane structure covered with regolith shielding has been proposed as a possible lunar habitat. This paper presents results from the static, frequency, and dynamic impact analysis of using nonlinear (large deformation) finite-element technique. The are presented, taking into account effects added mass stress stiffening because applied internal pressurization load. loading is analytically derived by considering moving object/debris/projectile hitting midpoint one frame members at crest structure. For frequency analysis, show that both affect mode-shape characteristics, where observed to be substantially larger than pressurization. static analyses, midspan th...
