Penalty stiffness
WebThe penalty method applies a force that is a function of the depth of penetration. In most codes, the force is linear, F = kδn, which has the desirable property of conserving energy. … WebThe following simple method for calculating the penalty factor works well for most problems: (11.44)α=1.0×104(to6)×max{diagonal elements in the stiffness matrix} It is also common to use (11.45)α=1.0×105(to8)×Young’s modulus Note that several trials may be required to decide on an appropriate penalty factor.
