BLAST RESISTANT DOOR Design

  1. Sep 19, 2006 #1
    Dear all

    i am studing in VJTI mumbai
    I am a production student

    I have given a problem on Blast resistant door design

    Input is Blast pressure is 450 psi for 100 ms(millisec)
    door size is 2100 mm x 1100 mm

    Can Dynamic load converted into Static load?
    if yes then what is that factor?

    if no then What is a procedure to verify the thickness of door is
    acceptable?

    waiting for reply
    plzzzzzzzzzzzzzzzzzz do help me

    Well one has 450 psi (2.1 m x 1.1 m) which gives a distributed load.

    The door must avoid buckling and shearing, and one would design it for peak stress in the elastic range.

    Would hertzian stress matter? Or would the frequency be too low for it to matter?
