<p>The soft biological tissue materials often exhibit intrinsic variability due to inhomogeties once subjected to large deformation For in-vitro specimens, the uncertainties and variability in these specimens are high which may be raised by many factors such as the death age of cadaver, preservation time, and some other specific factors regarding to the soft tissue specimens and also measurements [1]. Although hyper elastic material parameters that calibrated for each singular specimen using deterministic approach is useful, stochastic calibration based on Bayesian estimation allows to quantify the uncertainties in useful bonds and also gives the correlation for the calibrated parameters. Here, we quantify the uncertainties and calibrate the hyper elastic parameters for in-vitro human head skin specimens.</p>
