It is shown that the mechanical properties of calcium leaching and loaded concrete are determined by calcium leaching, load and coupling effect.
For calcium leaching and loaded concrete, the influence factors to stress at any point are elastic modulus, maximum strain, strain at this point and the degree of calcium leaching.
The durability of concrete structures is considerably affected by the accumulation of damage resulting from time variant external loading in conjunction with environmentally induced mechanisms such as moisture and heat transport, freeze-thaw actions, chemically expansive reactions, chemical dissolution or by the corrosion of the reinforcement.
Based on the experimental results on calcium leaching and coupled chemo-mechanical damage, material models equationted on a macroscopic level of observation, have been developed for numerical predictions of the life time of concrete structures.
Coupled chemo-mechanical damage constitutive relation of concrete under calcium leaching and load According Strain equivalent principle put forward by Prof.

However, there are more underlying factors to be considered for GFRP to be the alternative to metallic structures.
Understanding of the manufacturing process is important to determine the factors affecting the FWM performance like winding angle, material combination, geometric features, stacking sequence, the pretension of fire and the amount of resin on impregnation of fiber [1].
The failure mechanisms associated with the GFRP composite pipes was described within the properties considered and scope of the comprehensive study.
Complementary factors such as ultimate strength of pipes, type of supports, correction factors for thermal expansion, among others.
This advanced material is selected due to its superior mechanical properties and to overcome the corrosion issue of the metallic tubular structures.

However, titanium alloy has poor machinability owing to its inherent properties such as low thermal conductivity, high chemical activity, etc.
Especially short abrasive wheel life and severe ground surface quality are the most important factors impairing its grindability [2].
Table 2 shows mechanical and physical properties of these materials.
A number of key factors contribute to these results including: 15% higher strength of TC11 over TC4, the much higher ductility of TC11, especially TC11 has superior heat intensity properties when below 500℃ [3].

For instance, Chan et al [2] analyzed TWB's formability and weld-line's mechanical properties with different thickness ratios by experiments.
Parent Material Parameters' Affects on TWB's Formability Factors affecting TWB's formability was divided into three categories: forming process factors including blank holder force, drawing velocity and so on; sheets' thickness ratio and material parameters(k, r, n); weld-line conditions(performance, location and angle of weld-line).
b) n (strain hardening index) is a major parameter affecting material equivalent stress too.
Dynaform, the FE software is used to analyze sensitivity factors of parent sheets in this paper.
Ranges of each factors can reflect their influence degree to indexes.

In particular, the interaction of complex thermal and mechanical forces under service loading is one of the major factors affecting the lifetime.
INTRODUCTION The improvement of cast Aluminium alloys for cylinder heads mainly focus on optimized fatigue properties and lifetimes under complex thermal and mechanical loading in service [1].
Mechanical Behaviour, TMF ―The influence of the treatments on the TMF performance of AlSi6Cu4 can be summarised by the ductility factor which is the product of maximum stress and the mean inelastic strain, at N=Nf/2.
It must be noted that a high ductility factor does not consequently result in a long lifetime.
At 200°C only a factor of 1.5 is determined.

Research of the Roll System’s Flexural Coupling-Dynamic Modeling Yang Zhang1,a, Yan Peng1,2,b , Jianliang Sun1,c 1 National Engineering Research Center for Equipment and Technology of Cold Rolling Strip, Yanshan University, Qinghuangdao 066004, Hebei, China 2 The state key laboratory of mechanical transmission, Chongqing University, Chongqing 400044, China azy-ce@163.com, Corresponding author: bpengyan@ysu.edu.cn, csunjl_1981@163.com Keywords: Roll system; Dynamic property; Vertical vibration; Lateral flexural vibration; Coupling.
The vertical vibration and the roller axial flexural deformation, among these dynamic responses, are the main factors which would affect the strip after rolling quality.
The roller system will produce different forms of dynamics responses, after external excitation such as system rolling force fluctuation, among which vertical vibration and bending and deformation along the roller’s axis are the main factors affecting the quality of finished strip steel.
Flexural Coupling-Dynamic Modeling For a more direct description of mill roll system’s flexural coupling-dynamic properties during vertical vibration, this paper studies one single roller, establishes lateral flexural coupling-dynamic model of roller during vertical vibration, and simplifies the roller as elastic beam model, shown in Fig.1 (a).
Analysis of steady-state response of anywhere along the roller body length under random vibration condition, indicates that roller’s amplitude sharply increases during around 0.049s, as shown in Fig.5 steady-state response properties of the midpoint and the both ends of the roller body.
