Three types of sandwich panels with different Continuum damage model graded corrugated truss core (the width of the core and inclination angle described by linear and exponential Bending strength functions) are designed and analyzed by the continuum damage evolution model. The influences of the geo- Graded corrugated truss core metric parameters on the load capacity and damage distribution of the graded sandwich structures with graded
