Inspired by the bionic Bouligand structure, helicoidal carbon fiber-reinforced polymer composite (CFRPC) laminates have been proven to own outstanding out-of-plane mechanical properties. This work aims to further explore the excellent bending characteristics of helicoidal CFRPC laminated plates and find out the optimal helicoidal layup patterns. The optimization design of laminated plates stacked with single-form and combination-form helicoidal layup sequences are carried out by using the finite element method (FEM) and adaptive simulated annealing (ASA) optimization algorithm on the Isight platform.

Article Synopsis
- The ear canal (EC) plays a critical role in hearing by facilitating sound transfer, but pathological conditions can alter its structure and affect sound pressure distribution and stapes footplate displacement gain.
- Research utilizing finite element models demonstrated that various surgical procedures, like canal wall down mastoidectomy, can change resonance frequencies and sound pressure gain, resulting in altered hearing outcomes.
- Stenosis (narrowing) of the EC significantly impairs sound transfer, particularly when located in various parts of the canal, showing that even minimal changes in EC morphology can have notable effects on hearing.

Osteoporosis (OP) is common with advancing age. Several studies have shown a strong correlation between OP and otosclerosis. However, no studies have investigated OP of the malleus, incus or stapes in the human middle ear, its effect on middle ear transfer function.

Objective: This study was to investigate the extrusion of the prosthesis from the tympanic membrane at post-ossiculoplasty by finite element method.
Methods: A finite element model of the human middle ear has been constructed and used as the model of the constructed middle ear at post-ossiculoplasty.
