| 摘 要： | The objective stress rate is a rather important problem in mechanics of finitedeformation.In this paper,the objective stress rate in co-moving coordinate is derived byapplying nonlinear geometric field theory of deformation.Problems.such ax largeextension coupled with rotation,and large shear deformation,are exemplified by using thenew formula.Comparing with Jaumann’s stress rate and other formulae presented incurrent literature,the new result appears to be the reasonable one in co-moving coordinatesystem.
