: In order to study the interaction mechanism of pile soil, the calculation of the pile soil system was built by the numerical method, the skin friction and axial stress distribution of pile were analyzed as well as the variation discipline of neutral point position and the soil displacement situation. The results show that the negative skin friction of pile first increases then decreases, and finally......

">Graphene has excellent theoretical properties and a wide range of applications in metal-based composites. However, because of defects on the graphene surface, the actual performance of the material is far below theoretical expectations. In addition, graphene containing defects could easily react with a matrix alloy, such as Al, to generate brittle and hydrolyzed phases that could further reduce......
