Calculation of large deflection of plates

Click For Summary
SUMMARY

The discussion focuses on calculating large deflections of simply supported plates, emphasizing the inadequacy of existing resources that primarily address small deflections (d ≤ t/2). The user seeks clarity on coefficients in formulas related to large deflection theory, specifically referencing a website (http://www.xcalcs.com) and a PDF document (http://www.ewp.rpi.edu/hartford/~bakm/PS/08_large.pdf) for further information. The complexity of large deflection theory for plates is acknowledged, indicating a need for specialized knowledge in this area.

PREREQUISITES
  • Understanding of large deflection theory for plates
  • Familiarity with structural mechanics
  • Knowledge of mathematical modeling techniques
  • Proficiency in using spreadsheet software for calculations
NEXT STEPS
  • Research the coefficients used in large deflection formulas for plates
  • Explore advanced structural analysis techniques for plate deflections
  • Learn about finite element analysis (FEA) tools applicable to plate deflection
  • Review case studies on large deflection behavior in engineering applications
USEFUL FOR

Engineers, structural analysts, and researchers involved in plate design and analysis, particularly those focusing on large deflection scenarios in civil and mechanical engineering.

I want to calculate/preparing a spread sheet for large deflection of simple supported plates. I search for too many documents but all of them for small deflection d≤ t\2 (d deflection, t thickness of sheet). I found a website http://www.xcalcs.com/cgi-bin/tutti/x3calcs.cgi?d=i_4_2_1_0_0&l=en but it is not clear how found coefficient in formulas. b/a etc.

Thanks in advance for cooperations

Large deflection theory for plates (or beams for that matter) is very complex mathematically.
