Performance Study on Axial Compression of CFRP-Strengthened Concrete Columns
Hans Journal of Civil Engineering, 2015 通过对6个混凝土柱的静力加载试验，本文研究了碳纤维布加固对不同截面混凝土柱的力学性能的影响，分析了碳纤维布粘贴层数及短柱截面类型对碳纤维布加固效果的具体影响。结果表明：碳纤维布可明显提高混凝土柱的刚度和极限承载力，减小柱的竖向位移，减小柱的横向应变和纵向应变；当碳纤维布粘贴层数为两层时，其影响程度比粘贴一层时更为显著，但其提高程度不与加固面积成正比；碳纤维布加固对混凝土圆柱极限承载力和刚度的提高优于对混凝土方柱的提高。 Through the static load test of six CFRP reinforced concrete columns, the paper studies the CFRP reinforced concrete columns with different ...

Performance of tri-tubular conical energy absorber under axial compression
Journal of Mechanical Engineering and SciencesQuasi static axial compression loading on tri-tubular cone (TC) has been carried out using LS-DYNA finite element analysis method. Tri-tubular cones of three arrangements; the first arrangement (model TC-1) consists of cone heights of 50 mm, 75 mm and ...

Thermoreflectance Detection of Point Defects Resulting from Focused Ion Beam Milling
Advanced Engineering Materials, EarlyView.Focused ion beam (FIB) milling is a common tool for nanoscale material processing, however irradiation damage, redeposition, and contamination can occur. We use several characterization tools to show FIB‐induced effects beyond 1 mm from the milled area.

Analysis of Mesostructure Unit Cells Comprised of Octet-truss Structures [PDF]
, 2006 A unit truss finite element analysis method allowing non-linear deformation is employed to analyze a unit cell comprised of n 3 octet-truss structures for their stiffness and displacement compared to their relative density under loading.
