Numerical Fatigue Analysis for Crack Propagation on Ti6Al4V Panel Using XFEM Method

Macromolecular Symposia, EarlyView.
ABSTRACT The aim of this work is the validation of a numerical model based on the XFEM method for the prediction of crack propagation in mechanical components subjected to cyclic loads. Through careful bibliographic research, it was decided to take as a case study the analysis of the propagation of a crack passing through a panel in an additive ...

Exploitation of Rabbits at the Dawn of the Holocene: Evidence From the Font Voltada Site (Northeastern Iberia) Using Comparative Neotaphonomic Models

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT During the transition from the Pleistocene to the Holocene, hunter‐gatherer societies in the northeastern Iberian Peninsula increased the number of settlements and broadened their subsistence strategies. This period is marked by the appearance of terrestrial snail accumulations attributable to human harvesting, the expansion of specialized ...

Inferring breeding phenology and reproductive success from the emergence of juveniles in population monitoring

Oikos, EarlyView.
Phenological shifts caused by climate change are increasingly documented in wild populations. These events may be inferred by examining changes in population abundance and age structure throughout the breeding season, often using citizen science. However, several gaps still limit optimal use of such data.

Bird strike analysis : AN ANALYTICAL APPROACH

, 2016
Airplanes have a risk of encounter birds while flying, taking off or landing and to ensure a safe flight the engines have to sustain functionality after one or several bird strikes; one vital part in the engine is the first stage rotor and hence it has to withstand bird strikes. Commercial finite element codes with explicit time marching techniques are

Global analysis of annual survival among shorebirds reveals a negative effect of migration distance and a decline in recent decades

Oikos, EarlyView.
Annual survival is a key demographic parameter driving population trends in wildlife populations. However, despite numerous species‐specific or regional studies, global reviews of the factors affecting the survival of declining taxa remain scarce. Here, we investigated annual survival of fledged immature and adult shorebirds, a globally‐distributed and
