Pour a mug of java and join Dr. Henrique Reis of the University of Illinois at Urbana-Champaign (UIUC) for the annual Lester/Mehl Honor Lecture today at 9:00 a.m. EST.
His talk, “Non-Collinear Wave Mixing: Assessment of Thermal Damage in Dimension Stone and of High Temperature Hydrogen Attack Damage in Carbon Steel Pressure Vessels,” will cover the use of nonlinear acoustics for materials characterization including incipient damage and microdamage. Reis will present the results of two different studies: the assessment of thermal-induced damage in dimension stone, and the assessment of damage in carbon steel pressure vessels exposed to high-temperature hydrogen attack. Both studies used non-collinear ultrasonic wave mixing.
Throughout his career, Reis has been very active in ASNT and other societies. He has chaired the ASNT Research Council and served on the ASNT Board of Directors. He received the George L. Pherigo Tutorial Citation Award in 2002, the ASNT Research Council Award for Sustained Excellence in 2016, and the Materials Evaluation Outstanding Paper Award in 2015. He also received the 2015 ASME Founders Award presented by the ASME Diagnosis and Prognosis Division. He is a Fellow in ASNT, the British Institute of Non-Destructive Testing, and the Acoustic Emission Working Group.
At UIUC, Reis is the director of the Nondestructive Testing and Evaluation Laboratory and a professor with 41 years of experience. His research includes materials characterization, structural health monitoring, life-cycle management of materials and structures, and manufacturing process control.
The Lester/Mehl Honor Lecture was established in memory of the outstanding contributions to ASNT and the NDT industry by Horace H. Lester and Robert F. Mehl. Lester wrote numerous published articles, fostered techniques, and did seminal work in ASNT committees, and Mehl was the first person to use radium for gamma radiography.
