Constitutive laws

 
CivilFEM constitutive laws is related to the analysis type with which the designed materials will be calculated.
 
Constitutive laws, attached to materials, specified in this help guide are ahead:
 
 
In the content of this annex, not only theory about the linear elastic behaviour can be found but also formulation about the rate independent inelastic behaviour analysis.
 
Linear elastic analysis has been implemented for every material in CivilFEM.
 
The Rate-Independent inelastic formulation is related to every non-linear analysis, for materials implemented in CivilFEM, as well as:
