The effect of wave crest speed in breaking waves
Abstract The present work focuses on the evolution of the crest speed around large focal type water wave events. The phenomenon of crest slowdown around the point of maximum elevation is studied numerically using a boundary element model. The model is used to generate large design waves based on realistic ocean spectra.

A simplified thermoplastic pultrusion model is developed to predict thermal fields in glass fiber/polyethylene terephthalate (GF/PET) composites with reduced computational cost. By combining effective material homogenization, validation against literature data, and Gaussian‐process‐based optimization, the study reveals how heating limits, pulling speed,
