只需将应变能密度替换为合适的松弛能量密度W，即可将张力场理论纳入普通弹性膜理论中。当使用W作为能量密度时，在解决膜问题时不会出现压应力，并且在应变空间的某些区域中应力是单轴拉伸。的性质暗示着应力-应变关系的许多其他有趣的特征。
Tension field theory can be incorporated into the ordinary theory of elastic membranes merely by replacing the strain energy density by a suitable relaxed energy densityW. WhenWis used as the energy density, no compressive stress can appear in the solution of a membrane problem, and in certain regions of strain space the stress is a uniaxial tension. The properties ofWimply a number of other interesting features of the stress-strain relations.
