# MAT6 (deprecated)

Material Property ElementThis material model is deprecated. Please see for more information.

## Description

MAT6 lets you define a linearly elastic material model for NLFE elements that follows Hooke's law. This material model considers the beam element as an elastic line passing through the beam center line.

## Format

```
<MAT6
id = "integer"
e = "real"
nu = "real"
rho = "real"
/>
```

## Attributes

`id`- Unique material property identification number.
`e`- Young's modulus for the element.
`nu`- Poisson's ratio for the element. Default is 0.0.
`rho`- Element density.

## Example

The example demonstrates the definition of a MAT6 element.

`<MAT6 id="1" e="2.07e+5" nu="0.3" rho="7.810e-6"/>`

## Comments

- This material element defines a linearly elastic material that obeys the Hooke's law. Each element must have a unique material identification number.
- This material model can only be used with BEAM elements.
- This material model considers the beam element as an elastic line passing through the beam element's center line.
- This material model is computationally very efficient.
