The results obtained from the experimental data are by the consideration of Equivalent single layer theory (ESL). However for more precise results the Layer-wise theory are in good agreement for laminated composite material. For the laminated type composite the shear modulus and other associated properties of the stated material can be found by means of simulating the loading environment by FEM.
For simulation of multi-layer CFRP COMSOL Multi-physics or Abaqus can be used.
