Local continuum consistent peridynamics with bond‐associated modeling and dynamic fracture
GAMM-Mitteilungen, Volume 49, Issue 1-2, March/June 2026.Abstract This paper explores the theoretical foundations and practical challenges of peridynamics as a nonlocal continuum mechanics method. We establish connections between classical continuum mechanics principles and peridynamics formulations, with a particular focus on understanding how the pairwise force function in peridynamics relates to stress ...

Papers in Palaeontology, Volume 12, Issue 2, March/April 2026.Abstract The fossil record of coelacanths (Actinistia) is diminished by several nominal gaps that obscure vital information pertaining to the clade's evolutionary history. Latimeriidae, the family that includes the extant coelacanth Latimeria, in addition to the Cenozoic, has an outstanding missing gap of 50 myr during the Mesozoic, with no records of ...

Papers in Palaeontology, Volume 12, Issue 1, January/February 2026.Abstract The Late Cretaceous witnessed numerous transgression–regression sequences and the onset of a global cooling phase at the start of the Campanian. In the European archipelago, these environmental changes, combined with active plate tectonics, facilitated the formation of ephemeral land bridges that served as dispersal routes for a variety of ...
