Many engineering designs focus on the production of durable, ergonomic, and economical new materials. In today’s world where natural resources are rapidly decreasing, recycling waste materials is great importance. As a result bending test, sample’s return to its original dimensions shows plastic feature material. It was observed that tensile strength can be increased if speed injection machine ...
We have used the Mori–Tanaka method to study the effect of nonlinear interface debonding on the constitutive behavior of composite material with high particle volume fraction. The interface debonding is characterized by a nonlinear cohesive law determined from the fracture test of the high explosive PBX 9501. Using the example of the composite material with spherical particles subject to hydros...
background: obtaining optimal marginal adaption with prefabricated stainless steel crowns (sscs) is diffi cult, especially after removing dental caries or defects in cervical areas. this situation requires the use of an ssc after tooth reconstruction. this study evaluated microleakage and material loss with fi ve restorative materials at ssc margins. materials and methods: one hundred and twent...
