Friction force - temperature dependance

Index Friction force - temperature dependance Ver: 0

DESCRIPTION

Research in rheology has shown that, as well as the viscosity law depends upon the Temperature, the friction law might also depend upon the Temperature through the dependency of its slip coefficient. This menu allows you to define this dependency.

Two forms are proposed for this dependency: The Arrhenius law, and the approximate Arrhenius law.

OPTIONS

-1 Upper level menu

1 Modify Alpha

Modifies the energy of activation of the Arrhenius law.

2 Modify Ta

Modifies the scaling temperature of the Arrhenius law, i.e. the temperature at which H(T)=1.

2 Mofify T0

Constant to add to the Temperature to convert to an absolute scale. Only for Arrhenius.
