J. Cent. South Univ. Technol. (2008) 15(s1): 039-042 DOI: 10.1007/s11771-008-310-6 Plastic variational principle based on the least work consumption principle TANG Song-hua(唐松花)1, 2, LUO Ying... way of establishing different kinds of variational principles is to set up the extreme principle related to the studied problem. Based on a general new extreme principle-the Least work consumption......
