Acrylic

class Acrylic(*args, **kwarg)

Bases: Solid

A class representing Polymethyl Methacrylate (PMMA/Acrylic) material properties.

ultimate_tensile_strength

Maximum tensile stress the material can withstand before failure in Pa (75e6)

Type:

float

ultimate_shear_strength

Maximum shear stress the material can withstand before failure in Pa (55.2e6)

Type:

float

ultimate_bearing_strength

Maximum bearing stress the material can withstand before failure in Pa (0.0)

Type:

float

yield_tensile_strength

Stress at which material begins to deform plastically in Pa (75e6)

Type:

float

yield_shear_strength

Shear stress at which material begins to deform plastically in Pa (55.2e6)

Type:

float

yield_bearing_strength

Bearing stress at which material begins to deform plastically in Pa (0.0)

Type:

float

minimum_gage_thickness

Minimum manufacturable thickness in m (3.175e-3)

Type:

float

density

Material density in kg/m³ (1180)

Type:

float

Notes

All material properties are based on median values from manufacturer reported data. The bearing strength values are set to zero as they are typically not relevant for acrylic applications.

Definitions

‘Ultimate Strength’

The maximum stress that a material can withstand before failure

‘Yield Strength’

The stress at which a material begins to deform plastically
