Singular stresses at the tip can be a reason for a crack initiation in composite materials.
Introduction Composite materials contain sharp material interfaces, wherein the ends of layers or fibers or particles themselves can form tips that can be understood as sharp material inclusions.
Good knowledge of stress distribution in places of this kind is necessary for reliable assessment of safety of the composite materials.
Eigenvector for both materials then form one joint eigenvector vk=vk0,vk1.

Methanotrophs-bearing liquid cultivated from the aged refuse has been proved to be effective for improving methane oxidation ability of landfill cover materials, and this is significant for CH4 emission control in landfill site.
Sprinkling methanotrophs-bearing liquid on the cover materials such as the aged refuse can increase amount of methanotrophs in them and is advantageous to improve their methane oxidation ability[10].

Traditional education under the impact of contemporary science technology has evolved, so the inherent idea of using traditional education also should change.
Evaluation factors involve three aspects: for learning evaluation, the object of education is learners, its evaluation is the main content; for teachers evaluation, teachers are the main perpetrators of teaching activities, its teaching ability directly affects the effectiveness of education; for the evaluation of teaching content, it is not the same with traditional education, and network education is quite broad, which is not confined to the network courseware, it also includes a variety of network learning materials, at the same time, generally using formative assessment to evaluate the teaching content.

Introduction The transport of thermal energy across an interface between two different materials is playing an ever increasing role in thin-film and nanostructure device.
The Lennard-Jones parameters for materials B and C have been systematically modified: εB=α1εA, σB=σA, mB=mA, εC =α2εA, σC=σA, mC=mA, where α1 and α2 are proportionality constants.
Conclusion In summary, Nonequilibrium molecular dynamics (NEMD) approach is developed to investigate the thermal transport across a solid-solid interface between two different materials with an interlayer around it.
Moreover, interface thermal resistance determined by the interlayer materials does not depend strongly on the simulation system size.

SiC-Ti functionally graded material (FGM) was prepared by polymer-derived method in order to resolve connection problem between the ceramic matrix and its composite materials, as well as metal at high-temperature.
Gradient materials were fabricated successfully by polymer-derived method combined with hot-press sintering process at 1300℃.
Several years ago, gradient intermediate layer (as called buffer layer) materials were used to reduce the residual stress of the connecting joints and improve jointing strength [1].
The SiC-Ti graded materials have reached the gradient of the initial request, because of the obviously gradual process of elements.
