I got it. The factor is absorbed in the definition of devStressInitialProd.

Thanks

 Hi 
 
 DruckerPrager3D::_calcStressElastoplastic has
 the following line
 
      
 const PylithScalar d =
         sqrt(ae *
 ae * devStressInitialProd + 2.0 * ae *
 
 This eqn in the manual, Eq.(5.110), has a
 factor of 2 in the 1st term.
 
 Thanks
