DERIVATION OF NONLINEAR RELATION BETWEEN DISPLACEMENT AND SIZE OF ELASTIC BODY ON ITS SELF WEIGHT BODY FORCE CONDITION

The relation between displacement of prototype and that of model if derived for the linear elastic body at its body force condition of self-weight based on the similarity theory.Accodding to the results of discussion of the equation representing the relation and analyse of a pillar body self weight compression, the nonlinear relation between displacement and size is obtained.
