	abstract = {The parameter identification of failure models for composite plies can be cumbersome,
		due to multiple effects as the consequence of brittle fracture. Our work proposes an
		iterative, nonlinear design of experiments (DoE) approach that finds the most
		informative experimental data to identify the parameters of the Tsai-Wu, Tsai-Hill,
		Hoffman, Hashin, max stress and Puck failure models. Depending on the data, the
		models perform differently, therefore, the parameter identification is validated by the
		Euclidean distance of the measured points to the closest ones on the nominal surface.
		The resulting errors provide a base for the ranking of the models, which helps to select
		the best fitting. Following the validation, the sensitivity of the best model is calculated
		through partial differentiation, and a theoretical surface is generated. Lastly, an iterative
		design of experiments is implemented to select the optimal set of experiments from
		which the parameters can be identified from the least data and minimizing the fitting
		error. This way, the number of experiments that is required for the model identification
		a composite material may be significantly reduced.
		We demonstrate how the proposed method selected the most optimal experiments
		through procedurally generated data. The results indicate that if the dataset contains
		enough information the method is robust and accurate. If the data set lacks the
		necessary information, novel material tests can be proposed based on the optimal
		points of the parameters' sensitivity of the generated failure model surface.},

	abstract = {The unstable behavior of the isotropic, compressible Mooney-Rivlin hyperelastic model is investigated and described. The constitutive equation is parameterized with the help of the ground-state Poisson’s ratio and the dimensionless ratio of the material parameters [Formula: see text] and [Formula: see text]. Transverse stretch solutions are obtained for standard homogeneous loading modes, and the stress solutions are computed numerically for the physically permitted range of the ground-state Poisson’s ratio. We introduce a numerical technique to isolate subdomains with non-unique transverse stretch responses. Our analysis revealed some limitations of the model and allowed us to make critical observations about the strengths and weaknesses of the model. The analyses we present are essential to understand the characteristics of this widely used hyperelastic model. The novel results have important implications for the application of the isotropic, compressible Mooney-Rivlin hyperelastic material model.},
