Abstract.
It is that build an independent contract unit mesh to part two different materials in different materials contract faces.
So as to make two different materials don not use common node any more in finite element model, in that case, there will be relative displacement between different materials, usually, we call it deformation inharmonious[4].

Although Silicon Carbide has become the material of choice for high power applications
in a range of extreme environments, the interest in creating active chemical sensors requires the
development of transistors for additional control circuits to operate in these environments.
Introduction Whilst the material properties of Silicon Carbide have made it the material choice for a wide range of high temperature, high power and high voltage electrical devices, the development of low voltage, low signal level structures have received relatively little attention.

Procurement processes in construction, which encompass the acquisition of materials, services, and labor, play a crucial role in determining project costs, quality, and efficiency, impacting every phase of project execution from tendering to contractor selection [3].
The adoption of effective procurement strategy in acquiring materials will ensure project success and client satisfaction [13].
