摘      要：A methodology for topology optimization based on element independent nodal density(EIND) is *** densities are implemented as the design variables and interpolated onto element space to determine the density of any point with Shepard interpolation *** influence of the diameter of interpolation is discussed which shows good *** new approach is demonstrated on the minimum volume problem subjected to a displacement *** rational approximation for material properties(RAMP) method and a dual programming optimization algorithm are used to penalize the intermediate density point to achieve nearly 0-1 *** are shown to meet stability,mesh dependence or non-checkerboard patterns of topology optimization without additional ***,the computational efficiency is greatly improved by multithread parallel computing with OpenMP.
