Work
His work began with his 1944 observation that "although very little force is required to detach Scotch tape from an adherend, the work expended in doing so is very large". This is from the elastic effects of the adhesive, on which he commented even if "one idealized the adhesive as a perfectly elastic material there appeared to be no body of mathematical theory which would provide a basis for calculations". Existing theories were only on very small deformations, so from 1945 to 1951, Rivlin was one of creators of the modern theory of large elastic deformations, including theory of Neo-Hookean solids and Mooney-Rivlin solids. He also made major contributions to the theory of non-Newtonian fluid flow, including in the Rivlin-Ericksen expansion.

Famous quotes containing the word work:
“You must work and do good, not be lazy and gamble, if you wish to earn happiness. Laziness may appear attractive, but work gives satisfaction.... I can’t understand people who don’t like work ...”
—Anne Frank (1929–1945)
“Most of our platitudes notwithstanding, self-deception remains the most difficult deception. The tricks that work on others count for nothing in that very well-lit back alley where one keeps assignations with oneself: no winning smiles will do here, no prettily drawn lists of good intentions.”
—Joan Didion (b. 1934)
“It seemed pathetic and terrible to me and it still does, that men and women work eight hours a day at jobs that bring them no joy, no reward save a few dollars.”
—Hortense Odlum (1892–?)
