Material (hwx.inspire)#

class Material(name='', **kwds)#

Bases: Named

A material is the physical substance that a part is made of, such as steel, aluminum, or plastic.

The type of material does not determine the visual appearance of a part, only its physical properties.

Base class for all user defined material.

Example

from hwx import inspire

model = inspire.newModel()
block = model.createSolidBlock()

# get default material
defaultMaterial = inspire.Material.getDefault()
print("Default material is: ", defaultMaterial.name)
print("Block material is: ", block.material.name)

# get a list of existing materials
avaliableMaterials = ""
for m in inspire.Material.getMaterials():
  avaliableMaterials += m + ", "
print("")
print("Available materials: " + str(avaliableMaterials[:-2]))

# assign material to block
aluminium = inspire.Material.get('Aluminum (7075-T6)')
block.material = aluminium
print("")
print("Block material is: ", block.material.name)

inspire.fitView()

destroy()#

Removes the material from the database.

Returns:: True, if deleted, else False.
Return type:: bool

property density#: Specifies density as a mass of a unit volume of a material.

property stress#

Specifies the yield stress of the material.

The stress value at which the behaviour of the material changes from elastic to plastic. It is the minimum stress at which a solid will undergo permanent deformation or plastic flow without a significant increase in the load or external force.

property youngModulus#

Specifies the young modulus of the material as a ratio of tensile stress and tensile strain.

This property of the material tells, how easily the material can stretch and deform.

property thermalExpansion#: Specifies the heat value on the material, when the size and volume increase in small increments.

property thermalConductivity#: Specifies the the rate at which heat is transferred by conduction through a unit cross-section area of a material, when a temperature gradient exits perpendicular to the area

property poissonRatio#: Poisson ratio is the ratio of the change in the width per unit width of a material, to the change in its length per unit length.
