Abstract: Calculation of the Element Stiffness Matrix Requires more computational effort because of handling large varying data. A new set of sampling points for the evaluation of 8 – node brick elements is introduced in this research study. A new set of integration points is a mimic of Gauss numerical integration method. The proposed set of sampling points is evaluated using the standard problems and compared with conventional Gauss numerical integration method and found that CPU execution time considerably reduced for the analysis of brick elements without compromising in the convergence rate, efficiency in the results and accuracy of values.
