Title:  Development of a Multiaxial Miniature Testing System in Investigating Deformation Characteristics of Micro Tubes

Date: August 15, 2016

Time & Location: 10 AM EB3-3115


This study proposes a multiaxial miniature testing system (MMTS) with the capability of prescribing axial force and internal pressure simultaneously to mimic the realistic μTHF loading conditions to determine relevant material properties of micro tubes. Specially designed grippers, loading frame, and pressurization system are applied in the testing system to realize the multiaxial loading function. The testing system is designed so that it can fit in a SEM for in-situ studies of the evolution in material microstructures of micro tubes under multiaxial loading condition. A 3-D digital image correlation system is supposed to be used for the strain measurement of multiaxial deformation on specimen surfaces outside of SEM. A novel hybrid heating method was developed to apply uniform elevated temperatures on micro tubes during the testing process.


Lin Li was born September 15, 1985 in Huojia County, Xinxiang, Henan Province, China. He graduated from Huojia NO.1 High School in 2006. Then he received his BS in Mechanical Engineering from Shenyang Jianzhu University in July 2010. After completing his undergraduate degree, he joined the graduate school at University of Dayton and received his MS in Mechanical Engineering in May 2013. In the Fall of 2013, he jointed the Mechanical Engineering program at North Carolina University to pursue Ph.D. degree. Since then, he became intrigued by metal working and machine design, including metal forming, and machining processes, tool&die design and material testing instrument design. He will receive his Doctor of Philosophy degree in Mechanical Engineering in August 2016.
