A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Advanced Engineering Materials, EarlyView.In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Egg Characteristics Which Influence Hatchability
Poultry Science, 1949 Abstract A MAJOR factor in the cost of production of chicks is the excessive loss of eggs which fail to hatch. It has been estimated that approximately 30 eggs of every hundred placed in commercial incubators fail to hatch. Approximately one half of the eggs which have to be discarded are infertile while the remainder represents eggs in which the ...

To increase hatchability of poultry
RUDN Journal of Agronomy and Animal Industries, 2013 The paper devoted to the study of how to increase hatchability of poultry presented development incubator for the withdrawal of young poultry. Presented a detailed description of known equipment, and upgraded its fragments. The proposed device has the following advantages: a more careful treatment of hatching eggs, with the exception of damage hatching
