Web15 Aug 2024 · Lower viscosity oil reduces parasitic losses, improving fuel economy and power. Parasitic losses are things that tax the engine’s power, think parasite, like a leach. Nice mental image now? Lower viscosity is easier to pump and to shear. This is why many heavy-duty oils are moving from the traditional 15W-40 to 10W-30. WebThe distinction between shear-locking and parasitic shear is not always made in the literature, and reduced integration is usually introduced as a way of encountering shear-locking. Reddy (1997) mentioned reduced integration as a way to eliminate shear-locking in beam elements. Also Pugh et al. WebThe existence of axial strain states in the shear strain interpolation function causes the parasitic shear effect. This bad property will lead to stiffen of the element (Dow, 1999). To grow the knowledge about parasitic shear error, formulation of the four-node rectangular element is examined in the coming lines. hdi retail on display
