| 1 | Evaluation Indicators and Extraction Method for Pitting Corrosion of Structural Steel显示文摘A set of evaluation indicators based on corrosion ratio in theory for assessing the extent of pitting corrosion and performance reduction are proposed. In order to quantify the morphology of pitting corrosion and extract the evaluation indicators,the 3D profile data obtained by pitting morphology measurement are imported into a special written program to automatically determine the location of each corrosion pit and distill any desired data pertinent to the pitting morphology. The results show that this method seems to be effective to analyze the corroded surface and characterize the pitting morphology. | Shanhua Xu Youde Wang Qifeng Xue | 2015 | Journal of Harbin Institute of Technology(New Series)2015，22，3： | 7 |
| 2 | Effects of Frost-damage on Mechanical Performance of Concrete显示文摘The aim of this study is to provide the quantificational change laws of strength,stiffness,and deformation capacity of frost-damaged concrete relating to a united index,the data were obtained by different researchers.Then the index of relative compressive strength(RCS) was introduced as the indicator of frost damage and a large number of mechanical performance testing data of frost-damaged concrete were collected and analyzed.By curve fitting,the correlations between RCS and the initial elastic modulus,the strain at peak compressive stress,and biaxial compressive strength,and tensile strength,and the strain at peak tensile stress were established.Thereafter,the analytical stress-strain response of frost-damaged concrete under monotonic loading was presented using RCS and compared with that of the experimental data.Moreover,an isotropic elastoplastic damage model of frost-damaged concrete subjected to repeated loading was established.Finally,we can systematically estimate the effects of frost-damage on the mechanical performance of concrete,which can be provided for the numerical simulation of frost-damaged concrete structures. | 李安邦 徐善华 WANG Youde | 2017 | Journal of Wuhan University of Technology(Materials Science)2017，32，1： | 1 |

| 6 | Global weak solutions to Landau-Lifshitz equations into compact Lie algebras显示文摘We consider a parabolic system from a bounded domain in a Euclidean space or a closed Riernannian manifold into a unit sphere in a compact Lie algebra g,which can be viewed as the extension of Landau-Lifshitz(LL)equation and was proposed by V.Arnold.We follow the ideas taken from the work by the second author to show the existence of global weak solutions to the Cauchy problems of such LL equations from an n-dimensional closed Riernannian manifold T or a bounded domain in R^n into a unit sphere Sg(1)in g.In particular,we consider the Hamiltonian system associated with the nonlocal energy micromagnetic energy defined on a bounded domain of R^31 and show the initial-boundary value problem to such LL equation without damping terms admits a global weak solution.The key ingredient of this article consists of the choices of test functions and approximate equations. | Zonglin JIA Youde WANG | 2019 | Frontiers of Mathematics in China2019，14，6： | 1 |

| 9 | Effects of Pitting Corrosion on the Fatigue Behavior of Q235 Steel显示文摘In order to analyze the distribution and characterizations of corrosion pits on the corroded surface,the steel surface data was measured. Based on the method of the interacting pits,the types of pits corresponding to different exposure time were observed and categorized for completely understanding the effects on the fatigue behavior. The results showed that the conditions for estimating whether the pits interfere with each other should not be ignored; exposure time with 2 years was a critical time. The exposure time and the interacting pits can observably reduce the fatigue life of corroded steel. From these conclusions,the method of fatigue crack growth rate with the multi-pits interaction(FCGR-MPI) was developed and used to predict the fatigue behavior of corroded steel affected with the interacting pits. The predicted lives were also well agreed with the experimental results. | Shanhua Xu Songbo Ren Youde Wang | 2017 | Journal of Harbin Institute of Technology(New Series)2017，24，1： | 1 |

| 11 | New geometric flows on Riemannian manifolds and applications to Schr?dinger-Airy flows显示文摘In this paper,a class of new geometric flows on a complete Riemannian manifold is defined. The new flow is related to the generalized(third order) Landau-Lifshitz equation. On the other hand it could be thought of as a special case of the Schr¨odinger-Airy flow when the target manifold is a K¨ahler manifold with constant holomorphic sectional curvature. We show the local existence of the new flow on a complete Riemannian manifold with some assumptions on Ricci tensor. Moreover,if the target manifolds are Einstein or some certain type of locally symmetric spaces,the global results are obtained. | SUN XiaoWei WANG YouDe | 2014 | Science China Mathematics2014，57，11： | 1 |
