Hello , I have a small query. I'm unable to figure out the proper boundary condition to be assigned for an all side clamped plate under uni-axial and bi-axial buckling load. The plate is assumed to be under a pre-buckling uniform stress distribution over the laminate thickness.
the boundary condition in some research papers are given as
condition 1: u=v=w=thetaX=thetaY=0 @ X=0,a and Y=0,b
condition 2: under uniaxial u=w=thetaX=thetaY=0 @ X=0,a and Y=0,b
under bi-axial v=w=thetaX=thetaY=0 @ X=0,a and u=w=thetaX=thetaY=0 @ Y=0,b
which of the above mentioned boundary condition do suit for call side clamped plates?
Another perception of mine is, if we choose condition 1 as the boundary restraint, the edges will nit be able to move in x- and y- direction then how buckling is feasible?
condition 2 can be found in: http://ac.els-cdn.com/S0263822316316762/1-s2.0-S0263822316316762-main.pdf?_tid=452d2c36-4b65-11e7-a521-00000aacb35f&acdnat=1496828578_8efa4b8ef00e0f890720069aece79943
while condition 1 is given in: Doi: 10.1088/0964-1726/25/10/105014
