FEA modeling for precision laser peening

LSP Technologies uses modeling to improve fatigue life for mission-critical parts, saving time and money in application development

Performance valve spring and FEA

Laser Peening a performance valve spring creates a compressive residual stress (blue in this FEA simulation) on the exterior of the wire where the stresses are the highest.

LSP Technologies, Inc. provides laser peening services and equipment, protecting hard-working parts from threatening forces in real-world operating environments.

Using finite element analysis (FEA), we can pinpoint exactly how to use laser peening to prevent corrosion, cracking, foreign object damage and high-cycle fatigue.

We can’t change the laws of physics, but we can slow down the effects of vibration, temperature, friction and other factors that try to assault your metal components.

Laser Peening Systems can extend the fatigue life of parts by more than 20 times the expectations for untreated parts.

To obtain those results, we collaborate closely with our customers in a process encompassing precision modeling, precision targeting, and precision execution of a laser peening strategy to extend fatigue life.

FEA modeling can play a key role in the process, matching a precise understanding of customer components with the benefits of laser peening technology.

Proton Radiography: real-time images for shock in metals

LSPT experts explore pRad potential for laser peening process

Can you make a movie to show the shock wave created by laser peening as it travels through metal? What would it tell you about how laser peening alters metal structures and adds to fatigue life?

While X-rays can’t show laser shock waves in real time due to the density of metals, scientists working in Proton Radiography, also referred to as pRad, can use protons to penetrate dense metals to find out more about how they react to shockwaves and explosions.

Los Alamos National Laboratory researchers invited two scientists from LSP Technologies, Inc. (LSPT) to learn more and contribute to the discussion at a workshop entitled “Proton Radiography (pRad) for Materials: Mesoscale and Beyond,” in Santa Fe, New Mexico, August 27-29.

Stan Bovid, LSPT Director of Materials Research, and Micheal Kattoura, LSPT Materials Research Engineer, attended  the symposium. The LSPT team discussed Laser-Driven Shockwaves in Materials, joining other experts in materials science, as well as specialists in additive manufacturing, proton radiography, shock physics, and mining.

LSP Technologies’ Portable Laser Peening System combats metal fatigue in hard-to-reach parts

The laser source for the Portable Laser Peening System provides adaptability for fiber optic transmission of the laser beam, as well as a smaller size.

The laser source for the Portable Laser Peening System provides adaptability for fiber optic transmission of the laser beam, as well as a smaller size — less than a meter long.

Fiber optics and custom tools will carry miniaturized laser peening technology to mission-critical components

Dublin, Ohio – August 6, 2018 – LSP Technologies is designing a new portable fiber-optic laser peening system to improve fatigue life and prevent cracking and corrosion for small, hard-to-reach parts in new applications.

The Portable Laser Peening System will include miniature mirrors, lenses, and water injection/extraction mechanisms for complex maintenance, repair, and manufacturing environments. This means the portable system will deliver effective laser peening with lower energy, higher pulse rates, and the maneuverability of fiber optics.

LSP Technologies Materials Research Engineer Micheal Kattoura

LSP Technologies, Inc.’s Micheal Kattoura presented findings on the stabilizing effects of laser peening for metal parts subject to high-temperature conditions at the 18th International Conference on the Strength of Metals (www.icsma18.org) July 16 at The Ohio State University’s Ohio Union.

Kattoura serves as a Materials Research Engineer for LSP Technologies (LSPT), providing expertise in both materials science and applied mechanics to quantify metal improvement benefits from LSPT’s laser peening systems in a variety of commercial applications.

“My research on this project underscored the benefits of the laser peening process for metal fatigue strength, even at elevated operational temperatures of 650℃ , or 1,200℉,” Kattoura said. “Metals we laser peened and tested at these elevated temperatures were able to retain a large amount of residual compressive stresses and stable microstructure created by the laser peening process.”
