Piston is a component of reciprocating engine and reciprocating pumps and other similar mechanisms. Piston is a vital component in an engine. Piston acts as a valve by covering and uncovering ports in the cylinder wall. Piston can be manufactured in two ways: Casting and Forging. The performance of the piston mainly depends upon the design and materials selected for manufacturing it. In this present work piston is designed in CATIA V5R20and further the analysis was carried out in ANSYS workbench. For carrying out the analysis three materials were selected, they are Aluminium, Grey cast iron, Structural steel. Static analysis was carried out and results are tabulated. Total deformation and Von -mises stress are calculated and found out that which materials suits for the assumedconditions.

In this paper, a computation method in failure analysis of layered composites containing pin-loaded holes. The investigation is focused on developing a reliable computation procedure to analyze initial failure load for pin-loaded holes at with layered and without layered composite structures. Finite element analysis (FEA) is used to determine stress distribution around the fastener hole. Combining soderberg curve model and Tsai-Wu initial failure criterion are used to determine joint failure. Special attention in this work is paid to pin-load distributions and its effect on the load level of failure and its location. In previous work initial failure analysis was carried out using cosine distribution between pin/lug mechanically fastened joint. Here contact finite element pin/lug model is analyzed. The influence of stacking sequences of layered composites containing pin-loaded holes is also investigated. Special attention is paid to failure load and mode analyses in composites with stacking sequence [0/ ± 90]s.
