Hill Engineering completed a rebranding process for our industry leading fatigue analysis software. The process produced a new name, BAMpFTM (Broad Application for Multi-point Fatigue), and a new logo.Continue reading BAMpF Rebranding
Hill Engineering’s Rapid Forge Design™ software is an automated tool for fast and reliable design of 2-piece, closed-die impression forgings. Rapid Forge Design™ reads the final part geometry and automatically designs a forging according to accepted industry guidelines and user inputs. Rapid Forge Design™ is intended for use by forging suppliers and forging consumers/OEMs.
The Rapid Forge Design™ software comes with a user-friendly, graphical interface that allows for forging designs using a simple, 3-step, menu guided approach.
The inputs to Rapid Forge Design™ are the 3D geometry of the machined part (to be manufactured from the forging) and critical, user-defined parameters that allow for customization of the resulting forging design (e.g., minimum thickness and minimum radius values).
The forging design is generated by Rapid Forge Design™ according to a set of prescribed, industry-accepted design rules. After the user inputs are provided, the automated forging design process is completed by Rapid Forge Design™ in minutes without any further user intervention. With this approach, Rapid Forge Design™ enables the design of forgings with significantly less effort than existing manual processes.
Rapid Forge Design™ outputs the 3D geometry of the forging and a host of useful forging statistics and properties including volume, plan view area, periphery length, heat treatment section thickness, and other dimensional information. These metrics are essential to support the quoting process (material producers) and planning and costing activities (OEMs).
The preliminary forging designs produced by Rapid Forge Design™ can be used as the starting point for the finished forging’s more detailed design and tooling CAD files.
The Rapid Forge Design™ process is outlined in the flowchart below. The operator can input and customize important design parameters including: web thickness, draft wall cover, draft wall angle, plan view radius, fillet radius, and corner radius. Default values are provided based on alloy dependent industry standards. Help menus provide additional support and guidance, where necessary.
Numerous examples taken from publicly available CAD files come with the software. The following are a few illustrations showing the ability of Rapid Forge Design™ to effectively produce forging designs for a wide variety of supplied final part geometry.

Unless you’re a sponge living under the sea, you probably don’t have an aquatic snail as your primary pet. That’s not the case in my household, however, where our only non-human friend is Sir Loin, the freshwater ramshorn snail.Continue reading HE Pet Spotlight: Sir Loin
Today marks a major milestone in the field of residual stress measurement. The contour method, one of the most useful and advanced residual stress measurement techniques, was first successfully implemented on this date (August 16th) in 1999 by Mike Prime at Los Alamos National Laboratory. The most significant feature of the contour method is its ability to generate detailed two-dimensional residual stress maps like the one shown below. Please join us in wishing the contour method a very happy 20th birthday! Continue reading Happy 20th birthday to the contour method

We’re putting something in a bottle, and no, it’s not an SOS to the world. It’s a strain gage!
Hill Engineering has recently developed technology to orient and apply strain gages inside a pressure vessel with restricted interior access. Continue reading Strain gage in a bottle
Hill Engineering recently contributed to a publication related to residual stress measurement in additive manufacturing (AM) test specimens titled, Elastic Residual Strain and Stress Measurements and Corresponding Part Deflections of 3D Additive Manufacturing Builds of IN625 AM‑Bench Artifacts Using Neutron Diffraction, Synchrotron X‑Ray Diffraction, and Contour Method. The work was performed under the NIST AM-Bench program in collaboration with researchers from NIST, Los Alamos National Laboratory, University of California Davis, and Cornell High Energy Synchrotron Source. The abstract text is available here along with a link to the publication. Continue reading Additive Manufacturing Benchmark Publication
Hill Engineering is presenting about residual stress aerospace forgings at the upcoming 2019 United States Air Force Structural Integrity Program Conference (ASIP) in San Antonio, TX. The 2019 ASIP Conference is specifically designed to bring together the world leaders in the area of aircraft structural integrity and to disseminate information on state-of-the-art technologies for aircraft structures in both the military and civilian fleets. Hill Engineering’s presentation will include a summary of recent work to quantify the residual stress variability in aerospace forgings. The abstract text is presented below. Continue reading ASIP Conference 2019
We would like to welcome Dallen Andrew to Hill Engineering. Dallen has 10 years of experience as a mechanical engineer supporting aircraft structural integrity programs. He received a BS degree in Mechanical Engineering from Utah State University in 2009, and a MS degree in Mechanical Engineering from the University of Utah in 2011.
During his career, Dallen has gained experience in many aspects of aircraft structural integrity, with specialization in the fatigue and fracture of metals. He has worked on many projects requiring him to utilize his capabilities in fatigue crack growth analysis, fracture mechanics, durability and damage tolerance analysis (DADTA), fatigue testing, continuing damage, residual stress, finite element analysis (FEA), and non-destructive inspection.
Dallen is an organizer of the Engineered Residual Stress Implementation (ERSI) working group developing the analytical framework to allow the benefits from deep engineered residual stresses to be applied to aircraft inspection intervals for the United States Air Force. Dallen has significant experience supporting the A-10 and T-38 aircraft fleets. He also has significant expertise in the use of AFGROW and NASGRO fracture mechanics and damage tolerance software packages.
