Plastic microlens arrays as a popular optical component has been used in wide range of devices because its low cost, high quality, and easy fabrication using simple methods. Although techniques for have advanced considerably recent years, non molding-based methods however are usually not suitable mass production. On the other hand, production rate, but these less capable creating complex compon...

The Disposal of large quantity of plastic cover may cause pollution of land, water bodies and air. The proposed concrete which is made up by adding plastic in concrete may help to reuse the plastic cover as one of the constituents material of concrete, to improve the certain properties of concrete. The properties of concrete as varying percentages of plastic will test for compressive strength a...

The results of the measurements spall strength polycarbonate at a maximum compression stress 0.6 GPa in initial temperature range 20-185 o C are presented. It has been found significant decrease when reached glass transition temperature. strain rates plastic wave determined depending on under single and stepwise shock compression. dependences velocity Us --- mass up stresses to 0.8 different te...

Since Ni-based single-crystal superalloys are anisotropic materials, their behavior in different crystal orientations is of great interest. In this study, the yielding behavior in both tension and compression for , and oriented materials at 500 °C has been investigated. The direction showed a serrated yielding behavior, a great tension/compression asymmetry in yield strength and visible deforma...
