Category: Residual stress measurement

In a recent blog post we discussed the question: what is residual stress. As a follow-up, today we are addressing the topic of residual stress calculation. Once you understand the concept of residual stress and are ready to account for its effect on material performance it’s important to quantify the residual stress that is present in your material. Residual stress calculation can include a variety of different topics. Continue reading Residual stress calculation

What is residual stress? That’s a very common question when you work at Hill Engineering. Many of our customers, friends, colleagues, and family members like to ask us questions about residual stress including: What is residual stress? How do you measure it? How does residual stress affect material performance? If you have questions about these topics, you’ve come to the right place. At Hill Engineering we love to talk about our work and we have a lot to share about residual stress. Continue reading What is Residual Stress?

Hill Engineering will be presenting at the upcoming Propulsion Safety & Sustainment Conference (PS&S) in Phoenix, AZ on May 22nd through May 25th. We invite you to come see us. We will be sharing some recent work about experimental validation of process models for nickel engine disk design. Hill Engineering’s presentation will include a summary of residual stress measurements used to calibrate and validate process models for nickel engine disk applications. The abstract text is presented below. Continue reading Come see us at PS&S 2017

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

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

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
