Evaluation of Singular Field Near Crack Tip by Intelligent Hybrid Method Based on Digital Image Correlation·Delaunay Automatic Element Division FEM

Abstract

In the experimental evaluation in transparent materials, generally optical techniques are often used. However, marine engine components are consist of metals, which are opaque materials. Therefore, visualization of stresses in metallic materials was almost impossible.In this paper, the intelligent hybrid method made it possible to visualize highly accurate stress and strain components in metallic materials.
