People following arthroscopic partial medial meniscectomy (APM) are at increased risk of developing knee osteoarthritis. High impact loading and peak loading early in the stance phase of gait may play a role in the pathogenesis of knee osteoarthritis. This was a secondary analysis of longitudinal data to investigate loading-related indices at baseline in an APM group (3 months post-surgery) and...

Whole bone morphology, cortical geometry, and tissue material properties modulate skeletal stresses and strains that in turn influence skeletal physiology and remodeling. Understanding how bone stiffness, the relationship between applied load and tissue strain, is regulated by developmental changes in bone structure and tissue material properties is important in implementing biophysical strateg...

BACKGROUND The objective of rehabilitation following meniscal repair is to promote healing by limiting stresses on repairs, while simultaneously preserving muscle strength and joint motion. Both protective protocols limiting weight bearing and accelerated which do not, have shown clinical success. This study assesses the effects of physiologic gait loading on the kinematic behavior of a repaire...

BACKGROUND A biomechanical study of three sternotomy closure techniques (figure-of-eight stainless-steel wires, Pectofix Dynamic Sternal Fixation [DSF] stainless-steel plates, and figure-of-eight stainless-steel cables) was conducted to compare strength and stiffness variables in three clinically relevant loading modes (anterior-posterior shear, longitudinal shear, and lateral distraction). M...

The destruction process of the rock by tool impact device occurs with an impulsive load on from recoil reaction side rock, not only in axial, but also transverse direction. A model part is considered, which takes into account and longitudinal oscillations. has form a rod for loading beam constant cross section loading. Transverse oscillations sections are considered independent. When calculatin...

Loading rates affect the behavior of concrete specimens from beginning loading process until failure. At rather high rates, longitudinal deformations in under a compressive load are practically elastic up ultimate limit state. It has been previously demonstrated that transverse effectively indicate high-strength entire static range. A theoretical model for cylindrical specimen failure load, bas...

The interosseous membrane (IOM) is a fibrous structure located within the forearm that possesses distinct direction and shape patterns. The membrane maintains the interosseous space between the radius and ulna through forearm rotations and actively transfers forces from the radius to the ulna. The interosseous membrane’s load transferring ability reduces the forces placed on the radiocapitellar...

In this paper, the cyclic fatigue hysteresis loops of 2D woven SiC/SiC ceramic matrix composites (CMCs) at elevated temperatures in steam have been investigated. The interface slip between fibers and the matrix existing in matrix cracking modes 3 and 5, in which matrix cracking and interface debonding occurred in longitudinal yarns, is considered as the major reason for hysteresis loops of 2D w...

Background: Excessive increases in weight bearing forces caused by obesity may negatively affect the lower limbs and feet but minimal research has examined the long-term loading effects of obesity on the musculoskeletal system, particularly in reference to the feet. Objectives: The purpose of the study was to investigate the effect of obesity on medial longitudinal arch of foot in young adults....

Abstract The paper is devoted to the problem of fatigue failure two-phase titanium alloy VT3-1 under action high-frequency cyclic loading. Samples for tests were made from compressor disk aviation engine D30-Ku installed on Tupolev Tu-154 planes. Repeated alternating loading was carried out by displacements small amplitude at 20 kHz, coinciding with first harmonic longitudinal elastic vibration...
