The problem of complete characterization of a general linearly elastic, anisotropic material is discussed. An experimental procedure of testing a normally oriented and an obliquely oriented cubical specimen of the material is proposed, from which the 36 constants in the compliance matrix can be determined. A multiaxial test cell for applying homogeneous compressive stresses to the cubical specimen is described and the procedure is applied to Scotchply, a reinforced plastic. The compliance matrix for Scotchply is determined and it is shown to be orthotropic.
