The S-R (strain-rotation) decomposition theorem has an ability to capture strain components and rotation components at the same time. Using the principle of virtual power (VP), in this study, a new formulation independent of specific numerical methods is proposed for the analysis of dynamic large or small deformation. Then, the formulation is applied to the discontinuous deformation analysis (DDA), yielding a new DDA based on the S-R decomposition theorem, abbreviated as SRDDAvp. Compared with the conventional DDA, SRDDAvpadopts a slightly modified basic variables together with the generalized-αmethod. The analysis of some typical examples indicates that SRDDAvpcan naturally overcome the issue of volume expansion, effectively improve the calculation accuracy and, equip DDA with the potential to treat large deformation.
