* 1452–1519 [[Leonardo da Vinci]] made many contributions.
* 1638: [[Galileo Galilei]] published the book ''[[Two New Sciences]]'' in which he examined the failure of simple structures.
* 1660: [[Hooke's law]] by [[Robert Hooke]].
* 1687: [[Isaac Newton]] published ''[[Philosophiæ Naturalis Principia Mathematica]]'', which contains his [[Newton's laws of motion|laws of motion]].
* 1750: [[Euler–Bernoulli beam equation]].
* 1700–1782: [[Daniel Bernoulli]] introduced the principle of [[virtual work]].
* 1707–1783: [[Leonhard Euler]] developed the theory of [[buckling]] of columns.
* 1826: [[Claude-Louis Navier]] published a treatise on the elastic behaviors of structures.
* 1873: [[Carlo Alberto Castigliano]] presented his dissertation "Intorno ai sistemi elastici", which contains [[Castigliano's method|his theorem]] for computing displacement as the partial derivative of the strain energy. This theorem includes the method of "least work" as a special case.
* 1874: [[Otto Mohr]] formalized the idea of a statically indeterminate structure.
* 1922: [[Stephen Timoshenko|Timoshenko]] corrects the [[Euler–Bernoulli beam theory|Euler–Bernoulli beam equation]].
* 1936: [[Hardy Cross]]' publication of the moment distribution method, an important innovation in the design of continuous frames.
* 1941: [[Alexander Hrennikoff]] solved the discretization of plane elasticity problems using a lattice framework.
* 1942: [[Richard Courant]] divided a domain into finite subregions.
* 1956: J. Turner, R. W. Clough, H. C. Martin, and L. J. Topp's paper on the "Stiffness and Deflection of Complex Structures" introduces the name "[[finite-element method]]" and is widely recognized as the first comprehensive treatment of the method as it is known today.
