04 Linear Viscoelasticity 1 Mechanical Models
academic.csuohio.eduThe Linear Elastic Solid (the "linear spring") The simplest way to create a model of a material is to suppose that it consists of nothing but a linear spring of stiffness E. The constitutive equation for the linear elastic solid is then simply E 1 The creep and recovery behaviour of the material to a suddenly applied load o is
Structural Dynamics of Linear Elastic Single-Degree-of ...
www.ce.memphis.eduspring is linear elastic. Real structures, especially those designed according to current seismic code provisions, will not remain elastic and, hence, the force-deformation relationship is not linear. However, linear analysis is often (almost exclusively) used in practice. This apparent contradiction will be explained as this discussion progresses.

Stress, Strain, and Strain Gages
www.me.psu.eduBeyond the elastic limit (or proportional limit), the material starts to behave irreversibly in the plastic deformation region, in which the stress vs. strain curve deviates from linear, and Hooke’s law no longer holds, as sketched. o In this learning module, only the elastic stress region is considered.
