strain energy method
1Engineering treatment of the finite element method — This is a draft of a new explanation as suggested on . The finite element method (FEM) is a technique for finding approximate solutions to differential equations that is particularly useful in engineering. As of 2005, FEM is the primary analysis… …
2Castigliano's method — Castigliano s method, named for Carlo Alberto Castigliano, is a method for determining the displacements of a linear elastic system based on the partial derivatives of the strain energy. In the mathematics of structures, he is known for his two… …

4Minimum total potential energy principle — The principle of minimum total potential energy is a fundamental concept used in physics, chemistry, biology, and engineering. It asserts that a structure or body shall deform or displace to a position that minimizes the total potential energy,… …
5Allylic strain — or 1,3 allylic strain in organic chemistry and its associated strain energy results from an unfavorable molecular conformation for the allyl group. The simplest representative of the allyls, propene, in its ground state has the methyl C H bond… …
6Helmholtz free energy — In thermodynamics, the Helmholtz free energy is a thermodynamic potential which measures the “useful” work obtainable from a closed thermodynamic system at a constant temperature and volume. For such a system, the negative of the difference in… …
7Solar energy — is the light and radiant heat from the Sun that powers Earth s climate and weather and sustains life. Since ancient times it has been harnessed for human use through a range of technologies. Solar radiation along with secondary solar resources… …
8Stress–strain curve — During testing of a material sample, the stress–strain curve is a graphical representation of the relationship between stress, derived from measuring the load applied on the sample, and strain, derived from measuring the deformation of the sample …
9High strain dynamic testing — is a method of testing deep foundations to obtain information about their capacity and integrity, and in some cases, to monitor their installation. It is codified by D4945 00 Standard Test Method for High Strain Dynamic Testing of Piles. High… …
10Directed-energy weapon — This article is about practical experiments with energy weapons. For fictional uses, see raygun. Humvee with Active Denial System mounted A directed energy weapon (DEW) emits energy in an aimed direction without the means of a projectile. It… …
