Identification of Nonlinear Dynamic Behavior and Failure for Riveted Joint Assemblies
Shock and Vibration, 2000 Many different types of rivets need to be modeled to analyze the crashworthiness of aircraft structures. A numerical procedure based on FE modeling and characterization of material failure constitutive models is proposed herein with the aim of limiting ...

Rupture by damage accumulation in rocks [PDF]
, 2006 The deformation of rocks is associated with microcracks nucleation and propagation, i.e. damage. The accumulation of damage and its spatial localization lead to the creation of a macroscale discontinuity, so-called "fault" in geological terms, and to the

Road transport vibration stress impact on ‘Palmer’ mangoes quality and shelflife [PDF]
Revista Brasileira de Fruticultura, 2021 Studying the causes of postharvest fruit loss is important to avoid reduction of quality and quantity for the consumer due, for example, to the influence of frequent impacts from vibrations during transportation.

Pre-fatigue influence on quasi-static tensile properties of Ti-6Al-4V in thin-sheet form [PDF]
, 2010 The response of engineering structures to loads is most often assessed without taking possible damage of the used material(s) into account. However, it has already been proved that a preceding cyclic loading and the alteration of the microstructure it ...

Matrix cracking in polymeric composites laminates: Modelling and experiments [PDF]
, 2007 Composites ability to retain functionality in the presence of damage is a crucial safety and economic issue. Generally the first damage mode in composite laminates is matrix cracking, which affects the mechanical properties of the structure long before ...

A new mechanical structural damage feature index based on HHT [PDF]
, 2018 A new damage feature index is presented for the structural health monitoring based on Hilbert-Huang transform (HHT). The energy marginal spectrum of the dynamic signal is used to construct damage characteristic parameter, which can reflect the signal ...

Mechanical strength of silica fiber splices after exposure to extreme temperatures [PDF]
, 2012 By using a combination of type-I and regenerated gratings, the mechanical strength of optical fiber splices after exposure to temperatures over 1300 C was characterized. Splice strength was found to decrease with temperature with a secondorder polynomial
