ComputeConstitutiveLaw(temperature, dtemp, stran, dstran, statev)[source]

Main function of the class: computes a new material state using a constitutive law solver from a previous material state and variations of temperature and strain

Parameters:

temperature (np.ndarray or list) – temperature at the previous state, at integration points (np.ndarray of size (nbIntPoints) or list of length nbIntPoints)
dtemp (np.ndarray or list) – variations of temperature between the previous state and the new state to compute, at integration points (np.ndarray of size (nbIntPoints) or list of length nbIntPoints)
stran (np.ndarray) – strain at the previous state, at integration points (np.ndarray of size (nbIntPoints,nbeOfDualComponents))
dstran (np.ndarray) – variations of strain between the previous state and the new state to compute, at integration points (np.ndarray of size (nbIntPoints,nbeOfDualComponents))
statev (np.ndarray) – internal state variables at the previous state, at integration points (np.ndarray of size (nbIntPoints,nbeOfStateVariables))

Returns:

np.ndarray – of size (nbIntPoints, nbeOfDualComponents, nbeOfDualComponents) ddsdde: local tangent matrix at the new state
np.ndarray – of size (nbIntPoints, nbeOfDualComponents) stress: stress at the new state
np.ndarray – of size (nbIntPoints, nbeOfStateVariables) statev: internal state variables at the new state

Parameters:: var (str) – key of the dictionnary for storing the variable (e.g. name of the variable)
Returns:: variable of the constitutive law
Return type:: custom_data_structure

SetOneConstitutiveLawVariable(var, value)[source]
