NASTRAN static and buckling analysis - comparison with other large-capacity programs [PDF]

, 1973
A square plate with clamped edges under a concentrated load was modeled using NASTRAN and ASKA finite element computer programs. Deflections were computed for various width-to-thickness ratios (b/t) of the plate element, and were compared against the ...

Metastable Ordered Mesoporous h‐LuFeO3 Thin Films Prepared by Soft‐Templating: Optical, Electronic, and Magnetic Properties

Advanced Materials Interfaces, EarlyView.
An intriguing design concept for the preparation of metastable mesoporous h‐LuFeO3 thin films and powders by soft‐templating is presented. The hexagonal rather than the orthorhombic phase is formed due to the presence of a polymer structure‐directing agent in the synthesis.
