This report aims to determine the fatigue life of a cubic lattice structure using a frequency-based analysis with numerical methods. The objective is to assess the endurance and reliability of the structure under cyclic loading conditions. The methodology involved the utilization of modal and harmonic analysis with Finite Element Analysis (FEA) to obtain the amplitude stress frequency response of the structure in the frequency domain. Subsequently, the stress response was transformed into the time domain to accurately represent the time-varying stresses experienced during the structure's operational life. The rainflow count algorithm was applied to identify and extract individual stress cycles, providing valuable data for fatigue life estimation. The key finding of the report is the visualization of the fatigue life of the structure in an S-N curve, representing the relationship between the applied stress level and the number of cycles to failure. The S-N curve serves as a critical tool for engineers to optimize the design and maintenance of the cubic lattice structure, ensuring its safe and reliable performance in real-world applications.
