A light-weight design method for vehicle with welded structure based on surrogate model Yuehua GAO1,2, Qipeng LIU3, Wenzhong ZHAO1 1School of Traffic & Transportation, Dalian Jiaotong University, Dalian 116028, Liaoning, P.R.China, gaoyuehua@djtu.edu.cn 2State Key Laboratory of Structural Analysis for Industrial Equipment, Dalian University of Technology, Dalian 116024, Liaoning, P.R.China 3School of Civil and Safety Engineering, Dalian Jiaotong University, Dalian 116028, Liaoning, P.R.China Keywords: vehicle structure; surrogate; optimization; weld fatigue; high-speed train) Abstract.
Weld fatigue analysis is performed by use of master S-N curve method in ASME criterion [7-8], which has mesh-insensitive property and is prone to use for engineering problems with more reliable evaluation results.
It has been applied early by a number of researchers in designing complex engineering [10–11].

Different Approaches to Numerical Simulations of Prestressed Concrete Structural Elements Filip Hokes Department of Structural Mechanics, Brno University of Technology, Faculty of Civil Engineering, Veveri 331/95, Czech Republic hokes.f@fce.vutbr.cz Keywords: Prestressed concrete; Bonded tendon, Finite element method; ANSYS; Beam element; Shell element; Solid element; Spring element; Link element.
Therefore, one of the engineering tasks is to define prestressing of concrete elements in FE software correctly and also effectively.
They can be used for almost engineering problems, but sometimes is their use inefficient.
The Solution of Prestressed Concrete Structural Elements Prestressed concrete allows engineers to design and subsequently build progressive structures.

Experimental study of remolded unsaturated soil subjected to wetting load under constant compression Xiumei Qiu1, a, Hanbing Bian2,b 1College of Hydraulic and Civil Engineering, Shandong Agricultural University, Taian 271018, China 2LEM3 (UMR CNRS 7239), Université de Lorraine, Ile du Saulcy, 57045 Metz, France aqxmxr@126.com, bbian@univ-metz.fr Keywords: remolded unsaturated soil, oedometer cell, wetting deformation, collapse.
Introduction In geotechnical practice most soils are in unsaturated condition, for example, the compacted soils used in several engineering constructions, such as the earth dams, highway, embankments etc.
However, a large number of engineering problems involve the presence of unsaturated zones.
