Reversed Cyclically Loaded Dowel-Type Fasteners
In contrast to nailed connections, little research has been done on bolted connections using a reversed cyclic loading scheme, although cyclic loading provides important information about energy absorption and damping properties, which is essential when analyzing seismic performance. Dowrick (1986) noted that the hysteretic characteristics for the primary connection of a subassembly govern its ...

متن کاملUltrashort echo imaging of cyclically loaded rabbit patellar tendon.
Tendinopathy affects individuals who perform repetitive joint motion. Magnetic resonance imaging (MRI) is frequently used to qualitatively assess tendon health, but quantitative evaluation of inherent MRI properties of loaded tendon has been limited. This study evaluated the effect of cyclic loading on T₂* values of fresh and frozen rabbit patellar tendons using ultra short echo (UTE) MRI. Eigh...
متن کاملModelling foundations of cyclically loaded biphasic tissues with multiplicative remodelling
For articular cartilage with the approximate material parameters HA = 1MPa, k = 1.0 · 10mNs and the sample radius relevant for current tissue engineering studies r0 = 2mm we find a characteristic time constant of τg ≈ 67min. For agarose with the same geometrical dimensions and the material parameters HA = 1.5 kPa, k = 6.61 · 10 mNs [2] we find τg ≈ 67min as well. These rough estimates show a co...
متن کاملMechanical testing of absorbable suture anchors.
PURPOSE Absorbable suture anchors offer great advantages but are made of mechanically weak material. The weakest link in the fixation of soft tissue to bone may therefore be the anchor itself. In this study, several commercially available anchors were mechanically tested in vitro. TYPE OF STUDY Biomechanical bench study. METHODS Twelve absorbable suture anchor models were implanted into an ...
