The compressive strength of articular cartilage [PDF]
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1998 Articular cartilage provides the smooth bearing surfaces in freely moving (synovial) joints. Its mechanical properties are important because structural failure of cartilage is closely associated with joint disorders, including osteoarthritis. Some mechanical properties of cartilage are well characterized, but little is known about its compressive ...

Anisotropic Concrete Compressive Strength
IABSE Reports, 2017<p>When the load carrying capacity of existing concrete structures is (re-)assessed it is often based on compressive strength of cores drilled out from the structure. Existing studies show that the core compressive strength is anisotropic; i.e.

Compressive strength of canine femur
Journal of Biomechanics, 1979Abstract This study is an in-depth analysis of the mechanical properties of the canine femur. The parameters studied were compressive strength, modulus of elasticity and density. The test specimens (4.5 mm long, 3 mm2 cross-sectional area) were prepared from eight different quadrants about the circumference of different levels of the proximal 2 ...

Compressive strength of atmospheric ice
Cold Regions Science and Technology, 2007Abstract Accumulation of atmospheric ice on power transmission lines is a source of tremendous damage to power networks. Despite the longstanding problem of atmospheric icing on network equipment, the mechanical properties and behavior of this type of ice under various loading conditions are still unclear.

Compressive strength of iceberg ice
Canadian Journal of Physics, 2003The uniaxial compressive strength of iceberg ice was determined over a wide range of strain rates from 108 to 10+1 s1 at 10°C. It was found that for strain rates less than 104 s1, strength increased in a power-law manner with strain rate. Above 104 s1, the strength was essentially constant at 4 MPa, dropping slightly between 103 and 101 s1 ...

The Compressive Strength of Ceramic Microbeads
Key Engineering Materials, 2007The compressive strengths of three kinds of ceramic microbeads, ZrO2 toughened mullite, zirconium silicate and industrial zirconia, were studied in this paper. The densities of these ceramic microbeads were 2.9, 3.5 and 5.3g/cm3. The weighted average of compressive strength of these ceramic microbeads was 446.9, 500.8 and 917.3 N/mm2.

Compressive strength model for concrete [PDF]
Magazine of Concrete Research, 2013 A predictive compressive strength model accounting for the type of cement, cement degree of hydration, aggregates type and gradation, mixtures proportion and air content was developed. This paper presents the formulation, implementation, calibration and validation of the proposed strength model for normal concrete.

Compressive strength testing of compressed earth blocks
Construction and Building Materials, 2007Abstract As with other masonry units, compressive strength is a basic measure of quality for compressed earth blocks. However, as compressed earth blocks are produced in a great variety of sizes the influence of block geometry on measured strength, primarily through platen restraint effects, must be taken into account.
