An upper-bound limit analysis of Mindlin plates using CS-DSG3 method and second-order cone programming
作者：
Highlights：
• CS-DSG3 is combined with SOCP for determining upper bound limit load of Mindlin plates.
• Limit analysis problem is transformed into an explicit form suitable for solution using SOCP and CS-DSG3.
• Numerical results show that CS-DSG3 is free of shear locking and can provide reliable upper bound collapse multipliers for Mindlin plates.
