fedoo.constitutivelaw.Spring

class Spring(Kx=0, Ky=0, Kz=0, name='')

Simple directional spring connector between nodes or surfaces

This constitutive Law should be associated with fedoo.weakform.InterfaceForce

Parameters:

  • Kx (scalar) – the rigidity along the X direction in material coordinates

  • Ky (scalar) – the rigidity along the Y direction in material coordinates

  • Kz (scalar) – the rigidity along the Z direction in material coordinates

  • name (str, optional) – The name of the constitutive law

__init__(Kx=0, Ky=0, Kz=0, name='')
