The analysis of forced vibrations of frameworks using finite element method is considered. The dynamic finite element, the base functions of which represent exact dynamic shapes of structural elements, is used for system discretization. The assessment of errors as a result of classic FEM application is given. The efficiency of application of dynamic finite element for analysis of forced vibrations and dynamic stress-deformed state of structures is shown.

This research represents a design and analysis of Automatic loading copper wire machine for the actuator arm (ALCM). The process of copper wire placement on a single actuator arm type compensates human workers. In this research, copper wire placement set is made as a 3D model by computer program before undergoes arrangement analysis via explicit dynamic finite element method to study a suitable speed for copper wire placing. It is considered by characteristics of copper wire after placed and failures occurred during the process that will define suitable speed of motor rotation. The suitable speed is corresponding to copper wire characteristic as preferred, prevent copper wire fracture and time reduction compare to human work.

In the present study, numerical solutions of the fractional diffusion and fractional diffusion-wave equations where fractional derivatives are considered in the Caputo sense have been obtained by a Galerkin finite element method using quadratic B-spline base functions. For the fractional diffusion equation, the L1 discretizaton formula is applied, whereas the L2 discretizaton formula is applied for the fractional diffusion-wave equation. The error norms L 2 and L ∞ are computed to test the accuracy of the proposed method. It is shown that the present scheme is unconditionally stable by applying a stability analysis to the approximation obtained by the proposed scheme.
