Hill Engineering will be presenting at the upcoming SEM Annual Conference and Exposition on Experimental and Applied Mechanics in Reno, NV from June 3rd through June 6th. We invite you to come see us. This conference focuses on all areas of research and applications pertaining to experimental mechanics, and has evolved to encompass the latest technologies supporting:
- optical methods
- additive & advanced manufacturing
- dynamic behavior of materials
- biological systems
- micro-and nano mechanics
- fatigue and fracture
- composite and multifunctional materials
- residual stress
- inverse problem methodologies
- time dependent materials.
Hill Engineering’s presentation will include a summary of recent work related to regularization uncertainty in slitting residual stress measurement. The abstract text is presented below.
This presentation describes the development of an uncertainty estimate for slitting residual stress measurement. The uncertainty estimate includes a newly developed uncertainty estimate related to the smoothing used in the stress calculation procedure called the regularization uncertainty. This work describes the approach to define the regularization uncertainty, shows the usefulness of the uncertainty estimate in a numerical experiment and a repeatability study. The uncertainty estimate is shown to meet an acceptance criterion that compares the calculated (measured) stress ± its uncertainty estimate to the true value for the numerical experiment or the mean stress from the repeatability study. This works shows the regularization uncertainty estimate to be a necessary contributor to the uncertainty in slitting and additionally the uncertainty estimate developed here reasonably predicts the uncertainty present in slitting method residual stress measurements.
are planning to attend the conference please stop by to discuss Hill Engineering’s
capabilities in fatigue analysis and design
and residual stress measurement

The upcoming SEM Annual Conference and Exposition on Experimental and Applied Mechanics will include a Pre-conference Course titled: Residual Stress 101. Scheduled for Sunday, June 2, 2019 from 9:00 a.m. to 5:00 p.m, the residual stress short-course aims to cover a broad, practical introduction to residual stresses for interested students, researchers and industrialists. Michael Prime, Michael Hill, Adrian DeWald, Antonio Baldi, and Cev Noyan will teach the course. Registration is currently open through the SEM website. Continue reading Residual Stress 101

We would like to welcome Jason Barker to Hill Engineering. Jason has 15 years of experience as a design engineer. As a Senior Engineer for Hill Engineering, Jason’s responsibilities will include: supporting the modification of A-10 legacy product definition to Model Based Definition (MBD) effort at Hill Air Force Base, working with A-10 engineers to develop and implement best practices and policy, providing guidance to subcontractors to ensure proper Computer Aided Design and Drafting (CADD) models are delivered to the government, and working with prime contractors to ensure a quality deliverable to the Air Force. Jason is also actively involved with implementation and management of Teamcenter Product Lifecycle Management (PLM) system within the A-10 community and supports the MBD (Model Based Definition) design effort on the A-10 Wing Replacement Program. Continue reading Welcome Jason Barker
