grains.abaqus.Material

class grains.abaqus.Material(from_Abaqus=False)

Adds, removes, modifies materials. Requirements: be able to - create an empty .inp file, containing only the materials - add materials to an existing .inp file

TODO: only document public attributes! .. attribute:: materials

materials, their behaviors and their parameters are stored here. Intended for internal representation. To view them, use the show method, to write them to an input file, use the write method.

type

dict

read(inp_file)

Reads material data from an Abaqus .inp file.

write(output_file=None)

Writes material data to an Abaqus .inp file.

remove(inp_file, output_file=None)

Removes material definitions from an Abaqus .inp file.

create(inp_file)

Creates empty Abaqus .inp file.

show()

Shows material data as it appears in the Abaqus .inp file.

Notes

The aim of this class is to programmatically add, remove, modify materials in a format understandable by Abaqus. This class does not target editing materials through a GUI (that can be done in Abaqus CAE).

__init__(from_Abaqus=False)

Parameters

from_Abaqus (bool, optional) – True if the input file was generated by Abaqus. The default is False. Abaqus generates input files with a consistent format. This allows certain optimizations: the input file may not need to be completely traversed to extract the materials. Third-party programs sometimes generate .inp files, which are valid but do not follow the Abaqus pattern. In this case, it cannot be predicted where the material definition ends in the file – the whole file needs to be traversed.

Returns

None.

Methods

__init__([from_Abaqus])	Parameters from_Abaqus (bool, optional) – True if the input file was generated by Abaqus. The default is False.

add_material(material)	Defines a new material by its name.
add_plastic(material, sigma_y, epsilon_p)	Adds metal plasticity behavior to a given material.
add_sections(inp_file[, output_file])	Adds section definitions to an Abaqus .inp file.
create(inp_file)	Creates empty Abaqus .inp file.
read(inp_file)	Reads material data from an Abaqus .inp file.
remove(inp_file[, output_file])	Removes material definitions from an Abaqus .inp file.
show()	Shows material data as it appears in the Abaqus .inp file.
write([output_file])	Writes material data to an Abaqus .inp file.
