Question W3–1: How does tripling the load affect the midspan displacement in
the linear analyses?
Answer: The midspan displacement is tripled in the linear analysis.
Question W3–2: How do the results of the nonlinear analyses compare to each
other and to those from the linear analyses?
Answer: The midspan displacement is not tripled in the nonlinear
analysis when the load is tripled; at the higher load, the value
of the displacement predicted by the nonlinear analysis is less
than the value predicted by the linear analysis.
Question W3–3: Why is the second entry on the first data line of the
;PLASTIC option equal to 0.0?
Answer: The first data line of the ;PLASTIC option defines the initial
yield point. The plastic strain at this point is zero.
Question W3–4: Where do the peak displacements and stresses occur in the
Answer: The peak value of U3 occurs at the midspan. The supports of
the plate are likely to be heavily stressed; this is confirmed by
contour plots of S11.
