Structural Linear Properties of Metals
Structural Linear Properties of Metals- Probably the
most basic and most used material properties are linear properties. Linear
properties used in simulation are usually the first step in testing a
simulation (looking for flaws in meshes, modeling, constraints, etc),
they consist of three to four values that are used as input: Modulus,
Poisson’s Ratio, density, and usually some type of yield criterion.
Linear properties are useful when a model undergoes only small strains
(stays within the linear portion of the curve). Linear properties can
be fleshed out by adding; shear properties, thermal properties, rate effects,
and many other properties. Some caution is advised when using linear properties
to failure, in that many materials have a component of non-linear behavior
prior to yield which cannot always be neglected.
