Major ampullate forcibly silked threads had ultimate strength (true breaking stress) of 1652±208 MPa, extensibility (true breaking strain) 0.52±0.22 mm/mm, initial stiffness (Young's modulus) 11.5±2.6 GPa, and toughness 354±93 J/cm3 (range 233 520 J/cm3) (Figs. 3 4).
The panel has ultimate flexural strength of 26 kN, exhibiting ductile behaviour.
From a biomechanical point of view, no graft material commonly used has ultimate failure strength or stiffness comparable to the native ACL.
The spun fibrous materials, containing a PGS core and PLLA shell, demonstrated J-shaped stress strain curves, and having ultimate tensile strength, rupture elongation, and stiffness constants respectively comparable to muscle tissue properties.
Commercial (99.2% pure) grades of titanium have ultimate tensile strength of about 434 MPa (63,000 psi), equal to that of common, low-grade steel alloys, but are less dense.
At confining pressures of a few kilobars or more and temperatures below 400°C to 500°C (i.e., within the serpentine P-T stability fields) experiments show that serpentinites are ductile, but have ultimate triaxial strengths of 0.5 to 1.4 GPa at T < 400°C (Raleigh and Paterson 1965; Murrell and Ishmail 1976; Moore et al. 1997; Hirth and Guillot 2013).
It is synthesized with a new catalyst, metallocene, and has a ultimate strength of ∼650 kg/cm2 at −80°C.
When the live load is applied near the intermediate support, the model bridge with a longer center span has higher ultimate strength.
When the live load is applied in the side span, the model bridge with a longer side span has higher ultimate strength.
In the comparison of the fully bonded NSMR specimens, CP1600-3 witripleplinesnes has higher ultimate strength than CP1600-1 with single line.
