StressUpdateBase is a material that is not called by MOOSE because of the compute=false flag set in the parameter list.
This class is a base class for materials that perform some internal computational procedure (such as an iterative returnmapping procedure) to compute an admissible state (which is usually an admissible stress that lies on or within the yield surface, as well as a set of internal parameters such as plastic strains). The computational procedure must return the admissible stress and a decomposition of the applied strain into elastic and inelastic components. All materials inheriting from this class must be called by a separate material, such as ComputeMultipleInelasticStress

Given a strain increment that results in a trial stress, perform some procedure (such as an iterative returnmapping process) to produce an admissible stress, an elastic strain increment and an inelastic strain increment.
If _fe_problem.currentlyComputingJacobian() = true, then updateState also computes d(stress)/d(strain) (or some approximation to it).
This method is called by ComputeMultipleInelasticStress. This method is pure virutal: all inheriting classes must overwrite this method.
strain_increment  Upon input: the strain increment. Upon output: the elastic strain increment 
inelastic_strain_increment  The inelastic_strain resulting from the interative procedure 
rotation_increment  The finitestrain rotation increment 
stress_new  Upon input: the trial stress that results from applying strain_increment as an elastic strain. Upon output: the admissible stress 
stress_old  The old value of stress 
elasticity_tensor  The elasticity tensor 
compute_full_tangent_operator  The calling routine would like the full consistent tangent operator to be placed in tangent_operator, if possible. This is irrelevant if _fe_problem.currentlyComputingJacobian() = false 
tangent_operator  d(stress)/d(strain), or some approximation to it If compute_full_tangent_operator=false, then tangent_operator=elasticity_tensor is an appropriate choice. tangent_operator is only computed if _fe_problem.currentlyComputingJacobian() = true
