The problem is :

  • in tiny displacements (the deformations of the structure ensuing from its loading area unit negligible and don’t have an effect on much, not its geometry),
  • quasi-static (no dynamic effect),
  • almost equal (no modification in temperature).

These simplifications permit straightforward and quick calculations, machine-controlled (by computer) or by hand. However, they’re generally inappropriate, in particular:
Highly heterogeneous or anisotropic materials area unit ofttimes used, like composite materials, wood, bolstered concrete;
some applications involve vital elastic deformations, particularly with versatile materials (composite materials, polymers), it’s then now not within the linear domain or that of tiny displacements.
