摘要
在本文中,我们建立m次速度空间中理想、完整、保守力学系统的新型积分变分原理,然后,我们把它推广到非保守系统、非完整系统和变质量系统,并建立弹塑性理论中类似的新型变分原理.
In this paper, we establish the new integral variational principle of ideal, holonomic and conservative systems in the m-order velocity space. Next we extend it to the nonconservative, nonholonomic and variable mass systems. Finally, we establish the similar new integral variational principle of elasticity and plasticity.
