  1. Improvement of the axial buckling capability of elliptical cylindrical shells

    … compared to the same cylinder constructed in isogrid fashion is demonstrated. In fact, recovery relative to an isogrid circular cylinder of the same circumference is demonstrated. For both approaches confirming finite element models are used to verify the findings. The two different approaches …

  2. Design, Analysis, Fabrication, and Testing of a Nanosatellite Structure

    … of the spacecraft uses a composite laminate isogrid structure as a method of structural optimization. This optimization method is shown to increase the structural performance by over 20%. We conduct several finite element analyses to verify the structural integrity. We correlate these …

  3. High-temperature superconductors as electromagnetic deployment and support structures in spacecraft

    … mass reduction occurs through the use of isogrid panels, aluminum or composites, and inflatable beams all reduce the mass of material necessary to build a truss or apply surface forces to a spacecraft structure. We instead look at using electromagnetic body forces generated by HTSs to …

  4. Bend-Forming: A Deformation Process for In-Space Manufacturing of Truss Structures

    … the compressive behavior of Bend-Formed isogrid columns through experiments, finding that the structures undergo a smooth formation of buckling deformations. Finite element analyses accurately predict the maximum loads observed experimentally, highlighting the imperfection-insensitive …

  5. Buckling Analysis of Composite Stiffened Panels and Shells in Aerospace Structure

    Stiffeners attached to composite panels and shells may significantly increase the overall buckling load of the resultant stiffened structure. Initially, an extensive literature review was conducted over the past ten years of published work wherein research was conducted on grid stiffened composite …
