The target of this research is to enhance of convergence speed of proportional topology optimization process since it usually spends much computational cost to reach the achievement. Conventionally, proportional topology optimization (PTO) is a non-sensitivity technique, in which, the material distribution is gradually optimized by certain amount of material at each iteration through the relationship between current maximum stress and allowable stress. This is a reason that PTO method took a long time to reach the optimal layout. This paper deploys an adaptive material amount to improve this point. The cantilever with fixed hole is used to validate the effectiveness of the new method. The result shows that the proposed technique provided a significant improvement on the performance of proportional optimization algorithm.
