Abstract Background Internal fixation is recommended for treating Vancouver B1 periprosthetic femoral fractures. Although several procedures have been developed with high stability and union rates, long-term weight-bearing constructs are still lacking. Therefore, the aim of present study was to evaluate a double-plate procedure using reversed contralateral locking compression-distal plates frac...

Externally bonding steel plates is a common method for strengthening old bridges. Structural features and diseases of T-beam bridge are described. The project Erdao River Bridge was taken as an example. Based on static load test, changes deflection stress studied at the bottom RC T-beams strengthened by externally in loading process. Numerical simulation also carried out. results test show that...

The particles in an elastic plate are permitted to move by a surface diffusion process subject to the constraint that the total free energy does not increase. The static equilibrium, the quasistatic linear stability, and the quasi-static nonlinear evolution of the surface are examined under different loading conditions: tensile/compressive or #exural. The equilibrium con"gurations are such that...

Abstract This study investigates stress‐based fatigue assessment methods to determine their applicability welded cover plate joints subject axial and bending loading. The nominal stress (NS), hot spot (HSS), 1 mm (OM), effective notch (ENS), theory of critical distances (TCD), averaging (SA) are covered, accuracy reliability evaluated. To the best authors' knowledge, there is limited test data ...

Ultra high molecular weight polyethylene (UHMWPE) is a material commonly used in total hip and knee joint replacements. Numerous studies have assessed the effect of its viscoelastic properties on phenomena such as creep, stress relaxation, and tensile stress. However, these investigations either use the complex 3D geometries of total hip and knee replacements or UHMWPE test objects on their own...

The human proximal tibiofibular joint (PTFJ) and its relationship to overall knee joint mechanics have been largely unexplored. This study describes force/displacement data from experiments done on four human cadaveric knee specimens and general conclusions obtained with the help of a statistical modeling technique. Specimens were rigidly affixed at the tibia to a force plate and the femur was ...

Enzymes from the matrix metalloproteinase (MMP) family play a crucial role in growth-plate vascularization and ossification via proteolytic cleavage and remodeling of the extracellular matrix. Their regulation in the growth plate is crucial for normal matrix assembly. Endochondral ossification, which takes place at the growth plates, is influenced by mechanical loading. Using an in vivo avian m...

The mechanical characteristics of coral reef sandy soil is significantly different from the sand and clay soils. Currently, Terzaghi's bearing capacity equation still commonly applied to evaluate reef, while calculation result not consistent with actual condition. Based on a port project in east Africa, plate loading test has been conducted P-S curves are obtained, values obtained results compa...
