Warrants caution in interpreting single-plane strain data from animal hearts; leaves open clinical translation of finite element methods.
The use of a nonhomogeneous finite element method significantly reduces measurement errors in cardiac strain distributions compared to homogeneous strain theory, which is crucial for accurate 3D stress analyses.
Waldman et al. (1993) studied this question.
