Item An Experimental Study of Design Strategies for Stiffening Thin Plates under Compression(University of Texas at Austin, 2019) Ramirez Chavez, Irving E.; Noe, Cameron; Sekar, Vigneshwaran; Jogani, Shainil; Israni, Siddharth; Bhate, DhruvIncreasing stiffness and failure loads while minimizing mass is useful in many engineering applications, including the design of thin plates and shells. In this paper, the performance of thin plates using a range of stiffening approaches were studied for the specific instance of compressive loading. Periodic, graded, stepped, “Voronoi” stochastic, and topologically optimized patterns were explored. These stiffening designs were realized using different software tools and manufactured with the Selective Laser Sintering (SLS) process. These 3D printed specimens were tested under compression to assess their mechanical response. Videos of these tests were recorded to study the shape of the failure modes. This data was analyzed to determine the performance of the different stiffener designs, in comparison to the performance of baseline plates without any stiffening. The study concludes with a discussion of the results and their implications for stiffening thin plates, showing that triangular and stochastic stiffening strategies show particular promise in increasing specific compressive stiffness and specific buckling load.Item General Considerations Prerequisite to Further Galveston Bay Shell Removal(University of Texas at Austin, 1969-07) Hill, F.R.; Masch, F.D.Item Letter to Alexander Comfort from H.B.
