Effect of contours on the mechanical behavior of metal extrusion additive manufacturing parts: A Study on notched 17-4PH stainless steel

Material extrusion allows for the fabrication of metallic parts with competitive cost and flexibility in setting fabrication parameters. However, the parts contain defects that are due to the deposition route itself, and to the removal of polymers…

Detecting water leaks in underground pipelines by radar and dielectric analysis

Water leaks in underground pipelines not only lead to economic losses from wasted water but can also cause structural damage to urban infrastructure. In this study, we present a non-destructive radar-based detection for locating water leaks beneath…

Identifiability Classes: A Novel Framework for Evaluating Parameter Identifiability

Finite Element Model Updating (FEMU) methods are a class of inverse methods that allows calibrating model parameters based on sensitivity analyses of an FE model. They have the advantage of being non-intrusive to the simulation model, and being able…
