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.

“Then, bringing me the joy we feel when wee see a work by our favorite painter which differs from any other that we know, or if we are led before a painting of which we have until then only seen a pencil sketch, if a musical piece heard only on the piano appears before us clothed in the colors of the orchestra, my grandfather called me the [hawthorn] hedge at Tansonville, saying, “You who are so fond of hawthorns, look at this pink thorn, isn’t it lovely?””
—Marcel Proust (1871–1922)
“I can’t work without a model. I won’t say I turn my back on nature ruthlessly in order to turn a study into a picture, arranging the colors, enlarging and simplifying; but in the matter of form I am too afraid of departing from the possible and the true.”
—Vincent Van Gogh (1853–1890)
