✔️ En este artículo, vamos a explorar el concepto de limite elástico en resistencia de materiales, un tema fundamental en ingeniería y ciencias aplicadas.
❄️ ¿Qué es el Limite Elástico?
El limite elástico se refiere al punto en el que un material comienza a deformarse plásticamente, es decir, sin recuperar su forma original después de la aplicación de una carga. En otras palabras, es el punto en que el material deja de ser elástico y pasa a ser plástico. Esto sucede cuando el material se somete a una tensión o esfuerzo que excede su capacidad elástica, provocando la deformación permanente.
📗 Definición Técnica de Limite Elástico
From a technical standpoint, the elastic limit is the point at which the stress-strain curve of a material begins to deviate from its linear elastic behavior. This means that beyond this point, the material will no longer return to its original shape after the removal of the applied load. In essence, the elastic limit marks the boundary between elastic and plastic behavior.
☄️ Diferencia entre Limite Elástico y Punto de Ruptura
While the elastic limit marks the transition from elastic to plastic behavior, the point of rupture refers to the point at which a material fails or breaks under stress. In other words, the elastic limit is a precursor to the point of rupture, as it marks the beginning of the degradation of the material’s properties.

The elastic limit is a fundamental concept in engineering, as it helps engineers determine the maximum load a material can withstand before it begins to deform plastically.
📗 Ejemplo de Limite Elástico
Here are five examples that illustrate the concept of the elastic limit:
- A metal rod is subjected to a tensile load. At first, the rod behaves elastically, returning to its original shape when the load is removed. However, as the load increases, the rod begins to deform plastically, and its shape no longer returns to its original form after the removal of the load.
- A rubber band is stretched to its elastic limit. At this point, the band begins to deform plastically, losing its elastic properties.
- A metal beam is subjected to a compressive load. At first, the beam behaves elastically, returning to its original shape when the load is removed. However, as the load increases, the beam begins to deform plastically, and its shape no longer returns to its original form after the removal of the load.
- A glass fiber is subjected to a tensile load. At first, the fiber behaves elastically, returning to its original shape when the load is removed. However, as the load increases, the fiber begins to deform plastically, and its shape no longer returns to its original form after the removal of the load.
- A plastic pipe is subjected to an internal pressure. At first, the pipe behaves elastically, returning to its original shape when the pressure is removed. However, as the pressure increases, the pipe begins to deform plastically, and its shape no longer returns to its original form after the removal of the pressure.
