Bayesian inference method enables single-shot characterization of cardiac tissue

Researchers have developed an unsupervised method called EUCLID to infer complex material properties of cardiac muscle tissue. This approach utilizes Bayesian inference to analyze data from a single biaxial test, significantly reducing the need for multiple specimens and extensive handling. The method accurately recovers material parameters with quantified uncertainty, even with noisy measurements, offering a more efficient and reliable way to characterize nonlinear orthotropic materials.

    Unsupervised full-field Bayesian inference of orthotropic hyperelasticity from a single biaxial test: a myocardial case study

    arXiv:2510.09498v3 Announce Type: replace-cross Abstract: Cardiac muscle tissue exhibits highly non-linear hyperelastic and orthotropic material behavior during passive deformation. Traditional constitutive identification protocols therefore combine multiple loading modes and typ…
