Purpose of the study After total hip replacement, the initial stability of the cementless femoral stem is a prerequisite for ensuring bone ingrowth and therefore long term fixation of the stem. For custom made implants, long term success of the replacement ...
Fiber push-out tests have been performed on a ceramic matrix composite consisting of Carborundum sintered SiC fibers, with a BN coating, embedded in a reaction-bonded SiC matrix. Analysis of the push-out data, utilizing the most complete theory presently a ...
The ball punch test technique was used to evaluate the conventional tensile and impact properties of the tempered martensitic steel EUROFER97 from room temperature down to liquid nitrogen temperature. The testing was carried out on unirradiated material on ...
The influence of particle size and particle type on the fracture toughness of aluminium matrix composites is investigated using model composites of 99.99% purity aluminium reinforced with particles of alumina and boron carbide. These composites are produce ...
A theoretical model and numerical methods were developed for testing different bone internal remodelling stimuli. The keystone of the study was the formulation of a stimulus based on the mechanical invariants of the stress tensor, which took into account b ...
A theory is presented to predict the stress/strain relations and unload/reload hysteresis behavior during the evolution of multiple matrix cracking in unidirectional fiber reinforced ceramic matrix composites (CMCs). The theory is based on the similarity b ...
The numerical simulation of concrete dams subject to earthquake loading requires realistic material laws which take into account material properties as effected by seismic action. Experiments under simulated seismic action were performed to examine the eff ...
This paper concerns the gage length dependence of fiber strength as established by measuring the fiber fracture stress vs. fragment length in the succession of fragments, which occur in tension testing of a single-fiber composite (s.f.c.). For fibers with ...
In the more recent applications of technical polymers, they are frequently submitted to high strain rates. Being viscoelastic by nature, their mechanical properties are rate dependent. It is therefore important to investigate their properties over a wide r ...
