Their concepts, culminating in functionally graded materials, have been successfully tested in aerospace propulsion engines, pressure vessels, gas turbine disks, thin films and coatings, etc.
Theoretical review High stresses develop ahead of the crack tip resulting in material plastic strain.
This was due to additional load transfer towards stronger materials on other side of weld interface I by eccentric loading over the crack.

In addition, they have low material costs and simple manufacturing processes and can be produced at low temperatures using simple equipment. [3] However, because of their low energy conversion efficiency compared to silicon-based solar cells, much research is being conducted worldwide to commercialize DSSCs.

Introduction MR fluids are suspensions of micron-sized, magnetizable particles in a carrier fluid such as synthetic oil and silicone oil, which are regarded as the intelligent materials that respond to an applied magnetic field with a change in their rheological properties.
For the flow field at Brz τσ < , the MR material behaves like a solid.

Under such dynamic conditions, the strain-rate dependence of material response causes the material behavior to be significantly different from what is observed under quasi-static conditions.
