Definition of elastica

(Harry H. Hull, "The Normal Forces and Their Ther...)

This has an interesting analogy with the assumption stated by Philippoff that `` the deformational mechanics of elastic solids can be applied to flowing solutions '' .

From this and the force of deformation it should be possible to calculate the elastic energy of deformation which should be equal to the * * f calculated from the pressure normal to the shearing face .

(Irving Stone, The Agony and the Ecstasy....)

his quill drawings had a scratchiness , suggesting skin texture ; the clay he used plastically to suggest soft moving flesh , as in an abdomen , in a reclining torso ; the wax he smoothed_over to give the body surface an elastic pull .
