Mesoscopic crack fracture criterion of high-speed railway concrete lining According to the number of the fatigue loads cycling times acting on the concrete materials, the fatigue is divided into 2 types: high-cycle fatigue and low cycle fatigue.
The high-cycle fatigue is that the stress level of cyclic loads is low and the stress cycling times reach before the fatigue fracture of materials or structure, the runway of airfield, the highway, the railway bridges and the highway road surface are among such fatigue mode.
The report of RILEM (The International Union of Laboratories and Experts in Construction Materials, Systems and Structures) thought that the fatigue failure of concrete materials is ascribed to two mechanisms: the adhesion degradation between mortar matrix and coarse aggregate, and the evolution of cracks in mortar matrix, these two failure mechanisms can occur alone or in combination [2].
The material properties were shown in table 2.

Introduction Honeycomb paperboard and EPE are two types of cushion packaging materials commonly used in the packaging industry, but their cushion mechanism and properties are different.
COMSOL Multiphysics had its own library materials, but Honeycomb Paperboard and EPE used in this research were not included, therefore, the properties of materials must be manually defined.
At the beginning of compression, the stress was small, two types of materials were at the linear elastic deformation stage, and the stiffness of honeycomb paperboard was much greater than that of EPE.

The tribological properties of nanofiber web with respect to fabrics and human skin or skin substitute material are also important for estimating the strength of shearing and comfort of clothing incorporating this material..
The effect of mating sliding materials on the friction coefficient of PU nanofiber web was investigated at a constant load of 0.78 N, which is the typical pressing force during tactile sensing of fabric by a forefinger.
Figure 7 show the typical friction signals of PU nanofiber web for various fabrics, artificial skin materials,and a human forefinger skin.
Stick-slip motion was observed for all the mating materials, but the frequency and magnitude of the signals depended on the mating material.

Introduction The development of pharmaceutical science is now mainly focused on drug delivery system since this could aid patient compliance and improve drug efficacy.
Material and Method Materials Virgin coconut oils or cold pressed-coconut oils were purchased from four different companies (A, B, C and D).
The acid value of each raw material was higher than its emulsion.
Some of physical and chemical properties of PE or RE were related with its original raw material.

With the increase of steam temperature and pressure, the materials that have good strength under high temperature creep are required.
So the key of ultra supercritical unit is to develop the materials which have the longer lives under high temperature and pressure [1].

Fortunately, some attempts to investigate the structural system and materials of Hagia Sophia have been made[1–5].
It is recognized that the structures of Hagia Sophia are comprised of at least two major classes of materials: granite stone, brick [8].
