Finite element analysis of fatigue damage of composite laminated structures [PDF]
Composite materials are increasingly believed to be the materials of the future with potential for application in high perfon-nance structures. One of the reasons for that is the indication that composite materials have a rather good rating with regard

A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Evaluating Energy Absorption Performance of Filled Lattice Structures
Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

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,

Knowledge-based fast finite element modeling method for ship structures
ObjectiveAs creating finite element models for the finite element analysis of ship structures is time-consuming and highly dependent on engineers' experience, this paper proposes a knowledge-based fast finite element modeling method to solve this problem.

Meso-scale finite element modeling of non-homogeneous three-phase concrete
Assumptionof material homogeneity is not realistic in study of the mechanical behavior of concrete. When a concrete specimen under loading condition starts to crack, it changes from a continuous state into a discrete one.
