課程簡介:
LS-DYNA除了強大的結構動力分析,可以處理汽車碰撞、電子產品落摔以外,還包含了許多物理場的分析能力,其中熱與熱固耦合是大家十分關心的項目。本次課程特別邀請LSTC 原廠專家 趙強生博士為我們介紹LS-DYNA 在處理熱問題上的功能。
課程包含thermal expansion stress analysis, thermal boundary condition, thermal solver, and more workshop problems like metal hot forming, thermal contact, pipe cooling等等。

講員介紹:
Dr. Qiangsheng Zhao
Dr. Zhao got his BS from Tsinghua University in 2006, MS from Michigan Technological University in 2008, and PhD from University of California, Berkeley in 2013. He joined LSTC in 2013 Summer, and have been working on heat transfer and carbon fiber.
