Abstract: Load cells are constructed using thin ring theories and are used in a variety of applications such as material testing machine calibration, force monitoring in various cutting instruments, agricultural applications, and loading in hardness testing machines, among others. Different ring-shaped load cells, such as square, hexagonal, octagonal, and circular load cells, were investigated using finite element analysis in this research. The study allows for the effect of shape over pressure, as well as deflection in the load cell. When strain is induced in different load cell components, the circular load cell is found to be the most responsive. In the octagonal ring, however, less defection is needed to achieve the same strain as in the circular ring. As a result, it is recommended that octagonal rather than circular shapes be used in the construction of load cells.
