A Splitting Architecture for Exact Reduced Coulomb Friction

Computer Graphics Forum, EarlyView.
Abstract Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its reduced form, exact Coulomb friction can be written as a cone complementarity problem with an augmented velocity, which reveals a natural split ...

Fatigue Behavior of Post‐Processed Additively Manufactured 316L Stainless Steel: Experiments and Fatigue Damage Modeling

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT This study experimentally and numerically investigates fatigue damage in additively manufactured 316L stainless steel produced by selective laser melting using the powder bed fusion–laser beam process. More than 100 specimens were tested under tensile and strain‐controlled fatigue loading to evaluate the effects of surface condition, hot ...

Continued population recovery and high annual survival rates of White‐rumped Vultures in Nepal

Ibis, EarlyView.
Populations of Gyps vultures in South Asia underwent catastrophic declines caused by unintentional poisoning by the veterinary drug diclofenac. Since the drug was banned in 2006–2010, declines have halted across the region, including in Nepal. The present study updates population trends of G.

Hatching failure and embryo mortality in endangered populations of Eurasian Curlew (Numenius arquata)

Ibis, EarlyView.
Hatching failure represents a significant and growing barrier to reproductive success in threatened birds and yet is often poorly understood. Populations of the Eurasian Curlew Numenius arquata in the United Kingdom and Republic of Ireland have experienced significant declines over recent decades, and low breeding productivity is a major barrier to ...
