Reliability consists of four components: failure-less operation, maintainability, durability, and preservation ability. For different machines conditions combinations these properties, differences in how they are balanced proportioned essential. tractors, the most important aspect reliability is while for agricultural machines, durability important. Using example a ploughshare, issue increasing...

Salt crystallization is one of the most important weathering agents and may limit the durability of building stones. Salt crystallization induces stresses inside the pores of stones. Consequently, stone durability is closely related to its physical properties and strength. The purpose of this study was to propose a statistical model for estimating stone durability against salt crystallization c...
