Fatigue Analysis

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

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
