Therefore analysis has to be carried out minored Teflon the weak regions and carry out necessary modifications to further improve the product. Hence, Finite Element Analysis(FEE) was used to analyses the ml coke bottle. The Strands Finite Element Analysis (FEE) software System is used by engineers, analysts and designers to perform engineering simulations, calculations and based on the results modifications are done to improve the quality and strength of the product in a short period of time. The software was invented in 1943 by R. Currant.
Moving on, based on the software many loading scenarios and pressure distributions can be determined. The properties of individual materials could also be inserted to give a realistic feedback of the design. FEE has become a solution to the task of predicting failure due to unknown stresses by showing problem areas in a material and allowing designers to see all of the theoretical stresses within. This method of product design and testing is far superior to the manufacturing costs which would accrue if each sample was actually built and tested thus this software was used to analyses a ml coke bottle.

Therefore the groups analysis is based mainly on two types of forces,that is hydrostatic force which is created by the presence of Juice and load force which acts directly on the bottle cap due to stacking of bottles. Hence keeping these loading effects in mind together with the appropriate restraining constraints the bottle was analyses with a base model and three other modifications looking at the areas of weakness. Fig. 1 Coca Cola bottle  Coke Juice bottle (ml) was chosen to be analyzed for the FEE project. The bottle was then cut out. Then the bottle that had been cut was traced on a graph paper and the coordinates was written.
Then the coordinates was plotted in strand 7 for analysis to be done. In order to start off with the plotting a reference point has to be selected with points at (O, O). Since the bottle was symmetrical only half of the bottle coordinates was taken. The coordinates were recorded and then plotted in strand 7. As soon as the nodes for half of the bottle are plotted then the beams were Joined by the beams. The cap is modeled as a brick due to the hardness of the cap and as well as the neck. For plates to form the beams were extruded and for bricks to form the pates were extruded.
For the cap to make to a brick an L-shaped plate was extruded. Before the extrusion takes place the subdivision had to be done into smaller parts. The purpose for the subdivision was for easier analysis purpose. Once the base of the model was made all the nodes were selected and fixed. Then a NON force is applied in the Y direction at the center of the cap. A hydrostatic force of 0. 0002 Amp was applied as face pressure (normal) to all the plates up to the level the Juice would be filled in the bottle The properties of the material were assigned to the bottle and the model was analyses.
The properties were as follows: For the plate: Modulus: 2. 8 Pittston Ratio: 0. 37 Density: 1. 4 For the brick: Modulus: 9 Poisson Ratio: 0. 42 Density: 8. 9 The model was solved and the results were recorded for the deflection in x and y erection, the plate and brick shear and as well as Von misses Stress. The three regions of concern were taken into account and modifications were done to them and the same results were taken for them and compared. The bottle (base model) was solved, the results for deflection in (X, Y) direction, plate and brick shear and Von misses Stress was noted.
