Structural integrity analysis of hole shape and location in lotus root

Hole shapes and their locations in lotus roots were studied and presented in this paper. The finite element method was used to study the effect of several factors on the structural integrity of a lotus root-like component. The factors considered in this paper include hole shape, number, size and location. The analysis of different structures was carried out using ANSYS software and assuming a porosity of 20% for each case. Stress values, effects of each factor and interactions between factors are discussed in the paper. The results from the analysis showed that engineering component design can be inspired by the lotus root which has several holes of different shape and size.
