Necessities in Design
Applied Technical Services performs finite element stress analysis to help clients validate their designs before production. Engineers design products and components with certain factors in mind, such as the type and magnitude of physical loads they will encounter in their intended usage conditions. Ensuring that they perform as required by their service environment means the difference between a successful design and impending structural failure. One of the primary methods used to forecast how well a design will withstand the stresses endemic to its service conditions is called finite element analysis; consulting engineering firms like ATS perform assessments using this method to help clients yield the most effective product possible.
About the Method
Also referred to by its acronym FEA, finite element analysis allows our engineers to simulate forces acting upon an object. This computer-assisted method takes a highly detailed 3D model of the subject of analysis (whether as small as a bolt or as large as a bridge) and applies loads comparable to those anticipated in the genuine article’s service conditions. The resulting map shows areas how stress concentrates as a result of the subject’s design, with warmer colors indicating zones with higher stress and cooler colors indicating lower stress. By applying known values — such as the design material’s physical characteristics (e.g., tensile strength) and the subject’s precise dimensions — and comparing them against relevant tolerances specified by a design code (e.g., ASME), our engineers can predict prevalent failure modes and project life spans. We perform FEA in the same facility as our chemical analysis, metallurgy, mechanical testing, and dimensional inspection services, allowing us to pass on savings to clients by gathering these datapoints in-house if they have not already been determined.
Not only can finite element analysis indicate the areas under the greatest stress when exposed to a load, but it can also simulate other phenomena. Vibration, liquid flow, heat transfer, and other stimuli can also undermine structural integrity over time — our team of engineers can replicate these using this method as well. Furthermore, FEA also has applications in failure analysis, as our investigators can use these simulations to help determine a root cause behind a component’s structural failure and mitigate the problem going forward.
ATS: A Trusted Finite Element Stress Analysis Provider
Since our founding in 1967, Applied Technical Services has provided consulting engineering to companies in need of our expertise and professionalism. We have enjoyed vast growth over the intervening 50+ years, thanks in no small part to the dedication of our valued employees. Not only has ATS expanded our list of capabilities to include testing, inspection, training, calibration, and forensic investigation, but we also serve clients around the world through the coordinated efforts of over 1,000 specialists from a variety of fields — a far cry from the three engineers aiding local businesses from their office in our founder’s basement. We answer the needs of clients from a variety of industries through our proficiency with finite element analysis, including:
Quality as a Priority
ATS dedicates ourselves to providing services of excellent quality. To this end, we perform all testing in our Marietta lab under the scope of our stringent quality management program. We keep our system registered to ISO 9001 — a status that we maintain by submitting our facility’s procedures to a schedule of routine audits by ISO-approved inspectors. This rigorous process helps us remain accountable to our clientele for the quality of service we deliver, as well as setting a foundation from which we can continually improve that quality.
To ensure we deliver the best customer experience, we uphold the following policies:
