Finite element method
The finite element method of analysis has created unmatched possibilities in analytic process; however it is not the best option to use in all cases. At times, there are other easier and more accurate approaches to solve problems; computation of stresses using simple flexural formulas instead of three-dimensional finite element analysis is one such example. There are situations when experimental results are required to find out the material properties involved in analysis, in such situations

Fukushima nuclear power station accident
However, the resulted tsunami damaged the emergency core cooling system. As Holt et al (2012) reported, the reactor vessel’s water levels drastically dropped and reached a level below the top of the hot fuel. Similarly, steam reacted with zirconium fuel cladding and produced huge amounts of hydrogen. It is the main cause of the hydrogen explosion that occurred at the upper part of the reactor building (ibid). Nearly after 12 hours, pressure inside the primary containment doubled to the

Stress results are not requires while displacement results may work, however, a rational approximation of the radius should be utilized in the model. In order to avoid this issue, model components can be made with a substance that can identify plastic bend, however, the pressure at the sharp re-entrant will continue to be unlimited. If stressors are not required, induction of a sharp re-entrant will not influence the results and simplification process will lead to simplify model, for instance,

Failure mode avoidance
In 2010, the company suffered a similar problem occasioned by the pedal entrapment malfunction. Since then, the company has conducted other recalls, and Ahsen, (2008) suggests that such incidences could have been avoided by implementing the Failure Mode and Effects Analysis programs. The FMA approach helps the manufacturers to identify high risk characteristics and develop appropriate measures to avoid potential failures. The current rules and regulations require the automotive industry to use

Materials used for the production of the rods were wood, bones and stones which have high densities and low youngs modulus. They have a low ratio of youngs modulus to the density that results in heavy rods that are cumbersome to use and transport. The materials are also brittle and required great care when transporting. Production of rods was mostly in small scale and for individual use.Modern production techniques for fishing rods use materials such as fibreglass composites, carbon fibre
