Mechanical Properties of Materials | MechaniCalc

The mechanical properties of a material affect how it behaves as it is loaded. The elastic modulus of the material affects how much it deflects under a load, and the strength of the material determines the stresses that it can withstand before it fails. The ductility of a material also plays a significant role in determining when a material

Effects of Processing on Microstructure and Mechanical

Vertically built samples were found to have no difference in UTS or YS compared to horizontally built samples, but the % EL was 30 % lower. Orientation within the x-y plane as well as location were found to have less than 3% effect on mechanical properties, and it is possible a second order effect of thermal mass contributed to these results.
