A tangent modulus method for rate dependent solids. (English) Zbl 0531.73057
Summary: A one step forward gradient time integration scheme is developed which leads to a tangent stiffness type method for rate dependent solids. Within the context of small strain theory numerical examples are presented showing application of the method to material behaviors ranging from elastic-nonlinearly viscous to nearly rate independent. The adaptability of this rate dependent tangent modulus method to complex constitutive relations and to finite deformation analyses is also illustrated.
