Kun Cheol Shin, introducted a failure criterion for anisotropic/isotropic bi-materials problem with a wedge.
But the process of obtaining the singular stress fields of anisotropic/isotropic bi-materials is complex.
The solid is composed of two materials, denoted by A and B, A-and B-materials are anisotropic and isotropic materials respectively.
The materials comprising the specimen are steel and glass fiber renforced epoxy composite material.

Introduction Geopolymers may represent new material types on the border among glass, ceramic materials and materials based on classical inorganic bonds [1].
Materials that use less natural resources, require less energy, and generate less CO2 are referred to as green materials.

Composite wicks are made of two or more materials or its layer configurations.
The familiar wick materials are copper, stainless steel etc which poses the capillary driving force.
The type of nano materials used to enhance the thermal conductivity is the ability of material to transfer heat which depends on its volume added with base fluid.
The temperature reduction at the evaporator was essential and is obtained with various temperature rise depends on the Nano materials used.
