Discussion of the Constitutive Relation on Cyclic Stress-Strain of engineering materials

工程科学学报 1989年第6期11卷 611-615页

作者：唐俊武王建国徐世平王枨北京科技大学北京

Based on the experimental results and analysis of the cyclic deformation, there is an obvious yield stage on the cyclic stress-strain curve at the stage of small plastic deformation (in room or low temperatures). This phenomenon is similar to that of monotonic tensile curve case. But for the former the deformation amount at which the yield begins is much smaller than that for the latter. The cyclic stress-strain constitutive relation needs to be further studied according to the actual cyclic stress-strain curve. The conventional constitutive equation σ=Aεn is based on the results only corresponding to the cyclic strengthening stage. It is not appropriate for the stage of the small plastic deformation and the stage of yield.

Frontiers of materials Science 2013年第4期7卷 313-334页

Over the past decade, there has been tremendous progress in developing advanced biomaterials for tissue repair and regeneration. This article reviews the frontiers of this field from two closely related areas, new engineering materials for bone substitution and biomimetic mineralization for bone-like nanocomposites. Rather than providing an exhaustive overview of the literature, we focus on several representative directions. We also discuss likely future trends in these areas, including synthetic biology-enabled biomaterials design and multifunctional implant materials for bone repair and regeneration.

Study on Landscape Application of Glass materials

引用

Agricultural Science & Technology 2015年第3期16卷 562-564页

作者：文雨晴雷凌华吴林鲜何珊刘洋雷雨菁湖南怀化学院生命科学系湖南怀化418008

Landscape architecture engineering materials change rapidly. Glass is a kind of isotropic amorphous homogeneous non-crystal materials which are of diverse types, complex composition, plasticity, mirror property, abrasion resistance, durability and texture. Therefore, more attention should be paid on the application of land- scape materials.
