Theroy of Tasi-Wu failure criterion Tasi-Wu failure criterion belonging to the theory of progressive failure, is most commonly used for failure analysis of composite materials in the software patran /nastran [2].
Compared with other theories for failure analysis, Tasi-Wu failure criterion not only analyzes the effect of difference between tensile strength and compressive strength on the damage to material, but also is most widely used in composite materials design.

Introduction The current challenge in designing new materials is concerned with the increasing use of light alloys in high-technology materials.
Methodology Material preparation The Mg–2Zn–xSn (x=0%, 2%, 4%) alloy was produced by permanent mould casting using high quality Mg (99%), Zn and Sn as raw materials.
Materials were obtained through the GARE project of the Ministry of Education, Government of Bangladesh.

Introduction CaP ceramic was preferred as implant materials because of its excellent biological properties [1].
Materials and methods The copolymer p-PPS-m-PPSA and the composites (HA-p-PPS-m-PPSA) were prepared by co-polymerization in NMP, described by above formulae [2].
There were many factors have significant influence on their bioactivity, biocompatibility and stability, including phase composition, structure defects, crystallinity, and porosity of the implant materials.
