Stress at which material begins to deform plastically in Pa (1500e6)

Type:

float

yield_shear_strength

Shear stress at which material begins to deform plastically in Pa (70e6)

Type:

float

yield_bearing_strength

Bearing stress at which material begins to deform plastically in Pa (1500e6)

Type:

float

minimum_gage_thickness

Minimum manufacturable thickness in m (420e-6)

Notes

This class implements material properties for unidirectional carbon fiber composites. The equal ultimate and yield strengths reflect the generally linear elastic behavior of carbon fiber composites up to failure. Properties are based on median values from manufacturer reported data.

Definitions

‘Unidirectional Carbon Fiber’

A composite material where all carbon fibers are aligned in a single direction, providing maximum strength along the fiber direction

‘Ultimate Strength’

The maximum stress that a material can withstand before failure

‘Yield Strength’

The stress at which a material begins to deform plastically (note: in composites, this is often equal to ultimate strength due to brittle failure behavior)
