Development of two-dimensional solver code for hybrid model of energy absorbing system

This paper treats the dynamic and energy absorption responses of nonlinear spring-mass system using a developed two dimensional solver code. The influence of spring stiffness and various mass configurations on the impact response was investigated using validated models. Results are quantified in terms of important impact response and indicate that an assembly of spring-mass system can be employed to examine the impact...

Structural numerical analysis of a three fingers prosthetic hand prototype

In spite of the importance of the finite element method analysis in the mechanical design, there are a few research works in the prosthetic hands design area that use this tool. This work uses the finite element method to perform a structural analysis of a prosthetic hand prototype during the cylindrical and tip grasp. Through geometric relations, a set of equations was developed in order to define the position of the...

Geoelectrical investigation of aquifer problems in Gosa area of Abuja, North Central, Nigeria

The study of aquifer problems in Gosa area of Abuja, North-central Nigeria, has been undertaken. Abuja, the capital city of Nigeria, is underlain by Precambrian basement rocks. Vertical electrical sounding (VES) was carried out at twelve locations within and around the Gosa area. The interpretation of the data obtained from the sounding revealed that six non-aquiferous geoelectrical layers overlie the unfractured...
