Aa. Elvin et al., EFFECT OF TRANSVERSE-SHEAR DEFORMATION ON ELASTIC-MODULI OF THIN ICE PLATES, Journal of engineering mechanics, 124(1), 1998, pp. 54-60
The elastic deformation of thin ice sheets due to bending and shear de
formation is considered. The in-plane Young's modulus and the transver
se shear modulus are calculated by least-squares fit of transverse pla
te deflection data. Results show that thin ice plates behave predomina
ntly in shear. Previously, the Young's moduli were calculated based on
bending theory alone. The Young's moduli of thin model ice sheets, es
timated using the bending and shear theory, are more than an order of
magnitude greater than calculated previously and hence are more realis
tic. Further, the previous ambiguity in the Young's modulus, arising f
rom fitting the data at various distances from the point of loading, i
s removed by considering shear and bending deformation.
