Generalised Hooke's law for an element of a shell
1983Introduction We are now ready to establish the mechanical properties of a typical small element of a thin uniform elastic shell. We have already decided to replace the shell itself by a model consisting of a surface, and we must now furnish this surface with appropriate mechanical properties.

Clavicular hook plates are frequently used in clinical orthopedics to treat acromioclavicular joint dislocation. However, patients often exhibit acromial osteolysis and peri-implant fracture after hook plate fixation. To solve the above problems, we developed a novel double-hook clavicular plate and used finite element analysis (FEA) to investigate its

Micron, 2019
Experiments involving scanning electron microscopy of the microstructure of barbules and optical microscopy of knotted barbules were conducted: the behaviour of knotted barbules, and their evolution to form a branch of hooked barbules and unhooked barbules were analysed. A growth model for a feather plume was proposed.

This letter evaluates the methodological shortcomings in the FEA research conducted by Ma et al. (2025) that contrasts hook plates with tension-band wiring for patellar fractures. Unresolved concerns consist of: uniform bone material characteristics simplifying biomechanics; static loads neglecting dynamic physiological forces; idealized fracture ...

Clinical Biomechanics
Proximal junctional kyphosis (PJK) is a common complication following long-segment spinal fusion, characterized by abnormal kyphotic angulation at the junctional level adjacent to the upper instrumented vertebra (UIV). Multiple risk factors, including construct rigidity and abrupt stiffness transitions have been implicated.

ELASTO-PLASTIC FINITE ELEMENT ANALYSIS OF HOOK'S JOINT
2015Bu çalışmada çeki demirindeki gerilme analizi sonlu elemanlar metoduyla yapılmıştır. Sonlu eleman modelinin kurulmasında dört düğümlü izoparametrik elemanlar kullanılmış olup interpolasyon fonksiyonu olarak ise Lagrange polinomları alınmıştır. Eleman ağının oluşturulması için ayrı bir proğram yapılmış ve elemanlar otomatik olarak elde edilmiştir. Sonlu

[Finite element analysis of a new shape memory alloy cervical hook for atlantoaxial instability].
Nan fang yi ke da xue xue bao = Journal of Southern Medical University, 2008The mechanics of a new shape memory alloy cervical hook for atlantoaxial instability was analyzed with finite element method on the basis of a three-dimensional model reconstructed from the images of CT scanning of an adult cadaveric upper cervical at 1-mm interval. The stress and displacement of every nodule and element in the course of deformation of
