And it is also complex to calculate the pushing force at arch abutment on dam abutment rock, because the uncertain factors as water pressure, sediment, variable temperatures and materials parameters are contained.
R is resistance which is the mechanical characteristic of materials themselves.
Its statistical parameters usually can be obtained directly form test materials.
It often is the function of some characteristic of loads and materials.

Introduction Adhesive joints are commonly employed in advanced structures due to requirements of lightweight materials, especially in automotive and aerospace industries.
A comprehensive understanding of the fatigue fracture process is needed in addressing reliability issues of adhesive joints, which is influenced by many different factors including adhesive layer thickness, different joining materials and loading conditions and exposure to environmental condition.
