Hummingbirds occupy a unique place in nature: They fly like insects but have the musculoskeletal system of birds. According to Bo Cheng, the Kenneth K. and Olivia J. Kuo Early Career Associate Professor in Mechanical Engineering at Penn State, hummingbirds have extreme aerial agility and flight forms, which is why […]

A probabilistic computational framework for the prediction of corrosion-induced cracking in large structures
Stress corrosion and SCC mechanism The stress corrosion process, as shown in Fig. 2, starts from the local breakage of the passive film. Under a corrosive environment, the metal is corroded and produce cations (\({M}^{+}\)) into the electrolyte as well as the electrons in the electrode. During service life, complex mechanical […]
Finite Element Analysis: Key To Engineering Design
Finite element analysis (FEA) is defined as the process of using mathematical calculations, models, and simulations to understand, analyze, and predict the behavior of an object, part, assembly, or structure under various physical conditions. This article explains finite element analysis in detail, how it works, its uses, and some of […]
