Fig. 7From: Efficient structural reliability analysis by using a PGD model in an adaptive importance sampling schema1D truss: error of PGD limit state function at the first design point approximation \(\varvec{\mu }_{h_0}\) over the number of PGD modes M and different PGD mesh discretization (itPGDrel-ref step 2 and 3). The number of linear elements in \(\Phi \), \(\lambda \), E is given in the legend (in x 361 linear elements)Back to article page
