Fatigue Life Estimation of Damaged Integral Wing Spar Using XFEM

Fatigue Life Estimation of Damaged Integral Wing Spar Using XFEM

This paper presents the application of the extended finite element method (XFEM) in crack propagation simulation on the integral wing spar that should replace existing differential spar of the light aircraft UTVA 75. Numerical model of integral spar was developed in software Abaqus. Stress intensity...
