Nearly, I determined the elastic modulus of beech by unaxial compressionwith strain gauge, but when I used the parameters in Abaqus to simulate the compression ,I cmpared the load-displacement curve between test and simulation, the diference is so big, the slipe of simulation curve is bigger than test, that is to say the stiffness in simulation is bigger than that in test, and i think the main problem lay in elastic modulus, however, the parameter I measuered is similar to others ‘。could anyone give me some advice about it ,thaks very much.

@Martin Baeker ，the slipe of Elastic deformation is also bigger than test, you can see it in picture

Hu, what type of constitutive model are you using currently? This plot is for compression?
