WebThe figure below shows the stress-strain curves under uniaxial extension for the Neo-Hookean model and the 2-parameter Mooney-Rivlin model. For small extensions, both models provide similar stress-strain curves, whereas for strain values above 50 percent the Mooney-Rivlin model noticeably deviates from the fixed junction model. WebThe Mooney-Rivlin form can be viewed as an extension of the neo-Hookean form (discussed below) in that it adds a term that depends on the second invariant of the left …
