This research presents a new method to improve analytical model fidelity for non-linear systems. The approach investigates several mechanisms to assist the analyst in updating an analytical model based on experimental data and statistical analysis of

Computational modeling and simulation is a central tool in science and engineering, directed at solving partial differential equations for which analytical solutions are unavailable. The continuous equations are generally discretized in time, space,

Truncation error is ubiquitous in computational sciences, yet, rarely quantified and often ignored altogether. By definition, it is the difference between the exact-but-unknown solution of continuous equations that one wishes to solve, such as conser

Advances in sensor deployment and computational modeling have allowed significant strides to be recently made in the field of Structural Health Monitoring (SHM). One widely used SHM strategy is to perform a vibration analysis where a model of the str

Info-Gap (IG) Decision Theory, introduced in Chap. 5, is used to formulate, and solve, the analysis of robustness in the early design of a mechanical latch. The three components necessary to assess robustness of the latch design (a system model, perf

Numerical simulations, irrespective of the discipline or application, are often plagued by arbitrary numerical and modeling choices. Arbitrary choices can originate from kinematic assumptions, for example the use of 1D beam, 2D shell, or 3D continuum

Validation experiments are conducted at discrete settings within an operational domain to assess the predictive maturity of a model that is ultimately used to predict over the entire operational domain. Unless this domain is sufficiently explored wit

While numerical modeling is an important tool in many areas of engineering, caution must be exercised when developing and applying these models. This is especially true when models are developed under calibration conditions, which is referred to here
