ABSTRACT
Concrete mixture is a device that homogenously combines cement, aggregate such as Sand or gravel and water to form concrete. In this project the strength analysis and structural analysis of concrete mixture cylinder is investigated by finite element analysis (FEA). The softwares used are PROE 4.0, HYPERMESH10 and ANSYS11. The
result of analysis revealed that remarkable deformations and stresses occurred along the y direction and z direction. To analyze the concrete mixer cylinder under the concrete loads. The stresses in concrete mixer and simulations are below yield strength by reducing the thickness of the cylinder from 10mm to 6mm.

Introduction
Concrete mixer also commonly called as an cement mixture is a device that homogenously combines cement aggregate such as gravel or sand with water to form concrete

Description
In this work static analysis of the concrete mixture cylinder is carried out. In the static analysis, the parameters such as the thickness of the cylinder. In static analysis the concrete load is converted in to pressure load and applied on the concrete mixture cylinder.
In this design, we need to design the concrete mixture cylinder in such way that it should withstand for concrete loading. By varying the thickness of the same cylinder and the von misses stresses and factor of safety are studied for this design.
Material properties of Mild steel
Youngs modulus = 20 MPa Poissons Ratio = 0.3
Ultimate tensile strength=600MPa

Modeling and Meshing
The chosen problem is considered as 3D solid model. With the dimensional parameters the structure is modeled in ProE wildfire3.0 modeling software as shown in Fig.1. The model is meshed for further analysis using a meshing package hyper mesh 10 with Shell63. The model consists of 4926 elements with 4994nodes.Fig.2.shows FE model of the concrete mixture cylinder under loading and subjected to constrain. Fig 3.shows the Shell 63element considered for meshing. The shell63 is defined by four nodes and each node is having six degrees of freedom (UX, UY and UZ) at each node translations in the nodal x, y and z directions, and rotations about the nodal x,yand z directions. The element has Plasticity, Creep, Swelling, Elasticity, Stress stiffening, Large deflection, Large strain, Adaptive descent, Initial stress import capabilities.

Conclusion
The following conclusions are drawn from the present work.

The maximum displacement induced 0.677 mm along y axis in a cylinder of thickness 10mm

The maximum deflection induced 0.794 mm along y axis under the same loading condition in the same cylinder when the thickness is6mm.

The maximum stress induced is 51.99 MPa which is less than allowable limits of 600 MPa. Hence the factor of safety is 11.54
li>
The maximum stress induced is 49.38MPa which is less than allowable limits of 400MPa. Hence the factor of safety is 12.16.
