I expect your structure is 3D printed. Where did the Young's modulus value come from?
Print solid tensile test coupons in different directions to obtain force-displacement data from multiple samples, and convert them into Stress-Strain data. You need to use an Instron type tensile testing machine with a proper extensometer to measure displacement in a 40 mm gauge length at the center. Show the data, labeled by print direction. You have to print with these coupons flat on the bed, with a 4 mm build height as well as vertical with a 170 mm build height and some off at other angles.
