Organizer: Sino-French Institute of Nuclear Engineering and Technology, Sun Yat-sen University

Language: English

Abstract:

With accelerating use of aeronautic and aerospace composite structures in the high-temperature operating conditions, numerous research works were published on heat transfer and thermal stress analysis of laminated composite plates and shells during the last three decades. Existing works mainly focus on the thermomechanical fracture problem of delamination or transverse cracking, but only few studies have been conducted on multiple delaminations and problems in which the delamination and transverse cracks interact. In this presentation, a Thermomechanical Extended Layerwise Method (TELM) will be introduced for the laminated composite plates with multiple delaminations and transverse cracks. The proposed method is applied to the steady-state thermomechanical problems, elastic and thermomechanical dynamic problems for isotropic and composite plates with transverse cracks and multiple delaminations.

About the speaker:

Dr. Dinghe LI, Associate Professor and Chair of Department of Aircraft, College of Aeronautical Engineering, and Civil Aviation University of China (CAUC) ， has focused on analysis theories and numerical methods for the composite structures. He finished his MSc at CAUC on the sensitivity analysis of composite structures in the state space framework, graduating 1 year early. His PhD was devoted to the impact damages of the composite structures. He was the first 2.5 years Ph. D. in School of Aerospace Engineering, Tsinghua University. Dr. Li is the author of nearly 50 journal papers, where 25 SCI are published as the first or corresponding author. Honors and Awards: The second level of “131” innovative talents project of Tianjin, China; “Blue Sky Young Scholar” support plan of CAUC (2015); “Young Scholar of Distinction” of School of Aerospace Engineering in Tsinghua University (2014); “Scholarship for Excellent Freshman” of Tsinghua University (2012).
