“…Gray Cast Iron is a ferrous material that contains more percentage of iron, having more weight used to resist vibrations which applies to crankshaft, engine block etc. Zhang et al to Narayana et al (Zhang et al 2013;Ahmed and Basim 2009;Szurgott and Niezgoda 2011;Kurbet and Krishnakumar 2004;Hamzwhei and Manochehr 2006;Rahman et al 2019;Narayana et al 2014;Jayale et al 2017) have discussed that the engine component design and analysis has gotten increasingly difficult. The engine piston is one of these components.…”

The engine block is a crucial component of internal combustion engines since it provides the source of power for the vehicle. The engine block is a solid cast element that contains the cylinders and their related components inside a cooled and lubricated crankcase. The majority of engine blocks are cast iron, a brittle rich material that can sustain greater variations and weights while also being vibration resistant. Energy is changed from potential chemical energy to mechanical energy in this step, which is heat produced from burning fuel in the form of mechanical energy. A large amount of energy may be lost during the firing of an engine. This must be assessed using CFD prediction techniques. For starters, significant thermal and structural stresses may be produced over the cylinder blocks and pistons. Prior to the fabrication of the specific Internal Combustion engine, the structural and thermal analysis aids in the failure analysis. The solid modeller Parametric-Creo is used to create the current and new engine block models. This technical chapter will cover the simulation and analysis of the structural and thermal consequences of each specified bore piston and cylinder block model. The effective stress and temperature analysis using the finite element method will be performed using current tools such as ANSYS workbench, ADSL, and Deform 3D, with the processes and analytical functions described utilising supplementary literature theories, which can be found here.

“…The counting of stress cycles is an important step which must makes possible to filter the information essential for the study of fatigue damage. It is for example recognized that only the successive maximum and minimum of the stresses undergone by the structure have a significant influence on its fatigue prediction (Calder on-Ur ıszar-Aldaca et al, 2020), (Rahman et al, 2008), (Cacko, 1999) (see Figure 1)…”

PurposeThe purpose of this scientific work is to simulate the fatigue damage under random loading taking into account the mean stress effect on fatigue lifetime and using the rainflow counting technique to assess the fatigue damage.Design/methodology/approachThe study of fatigue under random loading is based on same concepts which as constant loading with addition of damage summation. The damage of materials due a stress cycle depends not only on the alternating stress but also on the mean stress.FindingsThe cycles counting simulation method allows quantifying the hysteresis loops, even if for small amplitude stresses.Originality/valueThe cycles are low or medium; the damage occurs most often, the higher values of alternating stresses cause the most failure of materials.

PurposeThe purpose of this scientific work is to simulate the fatigue damage under random loading, taking into account the mean stress effect on fatigue lifetime and using the Rainflow counting technique to assess the fatigue damage by the Ansys software. The used material is aluminum alloy 6082-T6. A comparison with literature results has confirmed this investigation in this paper.Design/methodology/approachThe study of fatigue under random loading is based on the same concepts as constant loading with the addition of damage summation. The proportion of damage caused by a stress cycle depends not only on the alternating stress but also on the mean stress.FindingsAnalysis of the fatigue damage shows that the number of relative damage due to each cycle.Originality/valueThis paper aims to simulate the fatigue damage under random loading for aluminum alloys.
