      The distinction between linear and non-linear materials is based on how they respond to applied forces, particularly in the context of material deformation or stress-strain relationships. Linear materials exhibit a proportional response to applied forces. This means that if you apply a force to a linear material, the resulting deformation (strain) is directly proportional to the applied force (Hooke's law, small deformations...). Non-linear materials do not exhibit a proportional response to applied forces. The relationship between stress and strain is not a straight line, and it may change with the magnitude of the applied forces. Examples of linear materials include some metals within their elastic limit, while examples of non-linear materials include rubber, biological tissues, and certain plastics that exhibit complex responses to applied forces. Understanding the linear or non-linear behavior of materials is crucial in various engineering disciplines, such as structural analysis, material design, and simulations, where accurate predictions of material responses under different loading conditions are essential.
