Welcome Josh Hodges

by Adrian DeWald

We would like to welcome Josh Hodges to Hill Engineering. Josh has worked in the United States Air Force T-38 ASIP office (Hill Air Force Base) for the past 8+ years as a Structural Integrity Analyst. During his time in the T-38 ASIP office, Josh filled many roles including: developer of the Broad Application for Modeling Failure software and manager of the T-38 Damage Database, while also serving as a subject matter expert on the effects of residual stress on fracture and fatigue.

Fatigue Analysis

by Adrian DeWald

Fatigue is a material failure mechanism whereby repeated sub-critical loads nucleate and grow cracks that can ultimately lead to failure of a structure. Hill Engineering routinely performs fatigue analysis to quantify and predict fatigue performance of materials. State-of-the-art fatigue analysis is subdivided into categories, including durability (crack initiation) or damage tolerance (crack growth). The appropriate fatigue analysis for a given design depends on the application. Continue reading Fatigue Analysis

Come see us at AeroMat 2017

by Adrian DeWald

Hill Engineering is presenting about advanced manufacturing methods and their effects on residual stress at the upcoming 2017 AeroMat Conference in Charleston, SC. The event is organized by ASM International and is hosted by Arconic. Hill Engineering’s presentation will include a summary of recent programs where we evaluated the residual stress from a variety of advanced manufacturing methods. The abstract text is presented below. Continue reading Come see us at AeroMat 2017

National Museum of the US Air Force

Building a Quality System

by Adrian DeWald

As was previously discussed, Hill Engineering was recently awarded ISO17025:2005 accreditation for our Quality System. Developing a Quality System that is compliant with ISO is a significant effort, and at Hill Engineering we took it as an opportunity to improve the quality and documentation of our laboratory residual stress measurement services. Here’s a look back on some of the highlights in the development of our Quality System. Continue reading Building a Quality System

The Prime Room

by Adrian DeWald

Hill Engineering recently moved into a new facility in Rancho Cordova, CA. The new facility features a combination of laboratory, research and development, and office space; all of which are important as we work tenaciously to meet the needs of our current projects, while at the same time keeping an eye towards innovation and new opportunities. We have proudly named the primary conference room in our new facility the Prime Room, a fitting tribute to a special Hill Engineering collaborator, the inventor of the contour method, and inspirational figure, Mike Prime.

Hill Engineering achieves ISO 17025 certification

by Adrian DeWald

We are excited to announce that Hill Engineering was recently awarded ISO17025:2005 accreditation!

ISO/IEC 17025 General requirements for the competence of testing and calibration laboratories is the primary ISO standard used by testing and calibration laboratories. Hill Engineering was accredited by the American Association for Laboratory Accreditation (A2LA). Compliance with the ISO/IEC 17025:2005 standard provides an internationally recognized basis for laboratory accreditation. The standard is used to govern Hill Engineering’s Quality System and entails adherence to rigorous technical requirements. Continue reading Hill Engineering achieves ISO 17025 certification

Senior Design Project

by Robert Pires

Senior Design or Capstone Projects are a common culmination to an engineering degree. The general consensus is that the projects are beneficial for the students by providing a helpful learning experience and portfolio boost. Continue reading Senior Design Project

Residual stress analysis

by Adrian DeWald

Material fabrication processes like forging, rolling, extrusion, quenching, additive manufacturing, machining, and welding lock spatially varying residual stress fields into structural materials. These residual stresses can influence the way that materials perform (e.g., fatigue, fracture, distortion, and corrosion). Hill Engineering has developed expertise to support many different types of residual stress analysis, which we apply to help our customers manage residual stresses effectively in design. The following are some examples of residual stress analysis. Continue reading Residual stress analysis
