1. The configurational or strain energy can be estimated using molecular mechanics calculations. 2. The strain energy density function for an incompressible Mooney Rivlin material is 3. As the wetting layer thickens, the associated strain energy increases rapidly. 4. There are situations where seemingly identical conformations are not equal in strain energy . 5. Piezoelectric materials have the ability to transform mechanical strain energy into electrical charge. 6. Compounds with unusually large strain energy include tetrahedranes, propellanes, cubane-type clusters, fenestranes and cyclophanes. 7. Perhaps surprisingly, medium-sized rings ( 7 13 carbons ) experience more strain energy than cyclohexane. 8. A quantitative measure for angle strain is strain energy . 9. The strain energy density is simply the ratio of the strain energy and the enclosed volume. 10. This is known as having low strain energy .
