个人简介 / Personal information
娄燕山，2012年博士毕业于韩国科学技术研究院(KAIST)，博士导师：Hoon Huh（许薰）教授。
娄燕山博士提出了基于损伤断裂微观机理的、考虑最大剪应力影响的损伤断裂模型，构建并力推基于应力不变量的各向异性/非对称塑性本构模型，在轻量化金属的塑性本构和损伤断裂模型的构建与应用方面具有10余年的经验和研究基础。
2013年获德国洪堡基金会资助，2014年9月至2015年8月，作为洪堡****在德国科学院院士、多特蒙德工业大学A.E. Tekkaya教授领导的国际顶级成形技术与结构轻量化研究所（IUL），从事轻质金属的塑性本构和损伤断裂的实验设计、本构模型的构建以及有限元应用等方面的研究。
与Jeong Whan Yoon教授合作，提出了适用于镁合金、钛合金等HCP金属的各向异性-非对称塑性屈服准则，并系统的实验研究了轻质金属在剪切、单向拉伸、平面应变拉伸等应力状态损伤断裂的各向异性特性，提出数个各向异性损伤断裂模型来描述轻质金属塑性变形过程受力方向对断裂应变的影响，为轻质金属成形工艺的有限元分析、设计和优化，以及零件的轻量化设计提供了一定的理论基础。
娄燕山博士与Jeong Whan Yoon教授在2018年提出的各向异性屈服方程（Yanshan Lou, Jeong Whan Yoon, 2018. Anisotropic yield function based on stress invariants for BCC and FCC metals and its extension to ductile fracture criterion. International Journal of Plasticity 101, 125-155.），被国际著名商业有限元软件LS-DYNA采用，在2020年以后的LS-DYNA版本中可通过 *MAT_LOU_YOON_ANISOTROPIC_PLASTICITY 来调用。
在塑性力学领域顶级期刊Int.J.Plasticity发表论文5篇，两篇为ESI高被引论文，google scholar引用1100余次。2019年获以有限元方法创始人 O.C. Zienkiewicz教授命名的O.C. Zienkiewicz Award。

Yanshan Lou (Jul., 1983) graduated from Korea Advanced Institute of Science and Technology (KAIST) in Aug. 2012, supervised by Prof. Hoon Huh.
Dr. Lou proposed a micro-mechanism-inspired ductile fracture criterion to consider the mechanisms of nucleation, growth and shear-linking up of voids along the maximum shear stress. The criterion considered the effect of the largest shear stress on damage induced by plastic deformation, and the effect of the largest shear stress is correlated with the effect of the Lode parameter for the first time. Several modifications are developed to consider a changeable cutoff value for the stress triaxiality, fracture of four key stress states for sheet metal forming (pure shear, uniaxial tension, plane strain tension and balanced biaxial tension).
Dr. Lou, together with Prof. J.W. Yoon, also developed a yield function for anisotropic-asymmetric behavior of HCP metals in 2014, and a yield function for BCC and FCC metals to describe their anisotropic plastic deformation. Both yield functions are in forms of stress invariants, and accordingly their application in umat is quite simple and the computation cost is much lower compared with yield functions in forms of principal stresses.
The anisotropic yield function proposed by Dr. Lou and Prof. J.W. Yoon (Yanshan Lou, Jeong Whan Yoon, 2018. Anisotropic yield function based on stress invariants for BCC and FCC metals and its extension to ductile fracture criterion. International Journal of Plasticity 101, 125-155.) is implemented by the commercial software LS-DYNA. The material model can be used by material card of *MAT_LOU-YOON_ANISOTROPIC_PLASTICITY by LS-DYNA released after 2020.
Dr. Lou worked as an Alexander von Humboldt scholar in Institute of Forming Technology and Lightweight Construction (IUL) leaded by Prof. A. Erman Tekkaya between Sept. 2014 and Aug. 2015.
Dr. Lou also worked very closely with Prof. J. W. Yoon for three times and benifited a lot during cooperation.
Dr. Lou published 5 papers in Int. J. Plasticity (3 as first authors and 1 as corresponding authors) and two first-authored ESI papers among more than ten JCR Q1 papers. Google citation is more than 900.
