“…For a large deformation calculation in geotechnical engineering, especially using an explicit time integration method, this numerical error is acceptable. The obtained result is also compared with various reference solutions (da Silva et al, Prandtl , and Meyerhof ) and other numerical solutions (PFEM , MPM , ALE , iSPFEM , and eSPFEM using a node integration scheme). All results are located between the analytical solution obtained by Prandtl (( π +2) c u = 5.14 c u ) and the limit load obtained by Meyerhof ((2 π +2) c u = 8.28 c u ).…”

“…Since the SPFEM adopts the explicit integration scheme rather than the standard PFEM using the implicit integration scheme, it is reasonable that oscillations of the blue curve by SPFEM seem larger with respect to the oscillations of the curve of the standard PFEM. This can also be found in various calculations and comparisons . For a large deformation calculation in geotechnical engineering, especially using an explicit time integration method, this numerical error is acceptable.…”

“…Recently [56,124,126] proposed to use nodal integration rather than the Gaussian one to improve the preservation of historical variables. In nodal integration schemes, all variables (including stresses and strains) are stored at the nodes.…”
