| 1 | Effect of temperature on the compressive behavior of carbon fiber composite pyramidal truss cores sandwich panels with reinforced frames显示文摘This paper focuses on the effect of temperature on the out-of-plane compressive properties and failure mechanism of carbon fiber/epoxy composite pyramidal truss cores sandwich panels(CF/CPTSP). CF/CPTSP with novel reinforced frames are manufactured by the water jet cutting and interlocking assembly method in this paper. The theoretical analysis is presented to predict the out-of-plane compressive stiffness and strength of CF/CPTSP at different ambient temperatures. The tests of composite sandwich panels are performed throughout the temperature range from -90℃ to 180℃. Good agreement is found between theoretical predictions and experimental measurements. Experimental results indicate that the low temperature increases the compressive stiffness and strength of CF/CPTSP. However, the high temperature causes the degradation of the compressive stiffness and strength. Meanwhile, the effects of temperature on the failure mode of composite sandwich panels are also observed. | Xiaodong Li Linzhi Wu Li Ma Xiangqiao Yan | 2016 | Theoretical & Applied Mechanics Letters2016，6，2： | 2 |

| 9 | INTERACTION OF THREE PARALLEL CRACKS IN RECTANGULAR PLATE UNDER CYCLIC LOADS显示文摘This paper presents a numerical approach for modeling the interaction between multiple cracks in a rectangular plate under cyclic loads.It involves the formulation of fatigue growth of multiple crack tips under mixed-mode loading and an extension of a hybrid displacement discontinuity method(a boundary element method)to fatigue crack growth analyses.Because of an intrinsic feature of the boundary element method,a general growth problem of multiple cracks can be solved in a single-region formulation.In the numerical simulation,remeshing of existing boundaries is not necessary for each increment of crack extension.Crack extension is conveniently modeled by adding new boundary elements on the incremental crack extension to the previous crack boundaries.As an example,the numerical approach is used to analyze the fatigue growth of three parallel cracks in a rectangular plate.The numerical results illustrate the validation of the numerical approach and can reveal the efect of the geometry of the cracked plate on the fatigue growth. | Changqing Miao Xiangqiao Yan | 2013 | Acta Mechanica Solida Sinica2013，26，5： | 1 |

| 12 | Study on pure silica core optical fibers显示文摘An optimal refractive index profile of pure silica core optical fiber (PSCF) was de- signed, in combination with the characters of the modified chemical vapor deposi- tion (MCVD) process. Techniques of preform fabrication by a new furnace round heating MCVD process and fiber drawing process were reviewed. Difficulties in doping fluorine in silica, widening the depressed-index cladding and maintaining the index of fiber core were discussed. Methods used to overcome these difficulties were given at the same time. Additionally, the optimal refractive index profiles of PSCF were presented. | LI Jian ZHENG Kai CHANG DeYuan WEI Huai NING TiGang FU YongJun MAO XiangQiao YAN FengPing JIAN Wei JIAN ShuiSheng | 2008 | Science China(Technological Sciences)2008，51，1： | 1 |
