As the temperature rises, both the \u003Cstrong>yield strength\u003C\u002Fstrong> and the \u003Cstrong>modulus of elasticity\u003C\u002Fstrong> decrease. As a result, the load-bearing capacity changes continuously.\u003C\u002Fp>\n\u003Cp>XFEM4U calculates this process entirely iteratively. For each member, the temperature evolution over time is determined, after which the system automatically identifies when the member loses its load-bearing capacity.
