The frames can be analyzed for internal force, stress, and strain using the theory that has already been developed for the three types of members. Displacement analysis, when attempted through an extension of the formulas of the three member types, may become cumbersome, at least for some kind...
Due to a large number of cells when meshing a part and hundreds of scan tracks for a layer with complex geometry, great computational costs are needed. Therefore, most of the 3D FE models [34–37] and 2D FE models [38–40] simulate the temperature and thermal stress evolutions with a ...
Knee osteotomies are effective procedures to treat different deformities and to redistribute the load at the joint level, reducing the risk of wear and, co

conversion of the static strain data to a form that is useful in measuring dynamic strains can be a simple job or a baffling requirement. To obtain a simple conversion constant without the use of formulas, the following procedure, adapted from resist~nce calibration techniques, can be u3eful....

A new theory of linear elasticity is developed from the concept of asymmetric strain, which is defined as the transpose of the deformation gradient tensor to involve rotation as well as symmetric strain. The new theory basically differs from the prevailing micropolar theory or couple stress theory ...

Despite the simplicity in deriving the present solution, it is sufficiently accurate in comparing with previous rigorous solutions and finite element results. Also, if the biaxial stresses on the top and the bottom surfaces of the disc can be measured during testing, the biaxial stress/strain ...
