General response observed in cyclically loaded cohesive soils

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 ...

Title Pile Aging in Cohesive Soils

This technical note presents the results of a field investigation into pile aging in soft clay which was conducted over a period of ten years. Static load tests were conducted after the excess pore pressure generated by the installation of 6 m long driven concrete piles were fully equalised. These tests allowed the time-capacity aging profile to be established. A normalised capacity-time trend ...

Ultrashort 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...

Modelling 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...
