A measure of the elasticity of a material, defined as the ratio of stress (force per unit area) to strain (proportional deformation) within the proportional limit of the material.

Unlike Anglo-Saxon textbooks that often drowned the reader in index notation, Berrocal’s Elasticidad used a method of progressive abstraction. He started with the physical reality of a stretched bar or a twisted shaft and then introduced the tensorial formalism. For many students educated in the 1970s–1990s, his book was the Rosetta Stone that made the works of Timoshenko or Love finally comprehensible.
In academic forums (like Reddit's r/EngineeringStudents or Spanish-speaking Discord servers), users have created "new" compilations that combine the original Elasticidad text with solution manuals or supplementary lecture notes from Ortiz Berrocal's disciples.
