The multiaxial fatigue behaviour of thin laser beam welded tube tube specimens of the structural steel St35 was assessed according to the methodology of the fictitious weld root radius of rf=0.05 mm and the application of the Effective Equivalent Stress Hypothesis (EESH), especially considering the fatigue life reducing influence of out-of-phase loading in comparison to in-phase loading.
The laboratory specimen demonstrated the structural effectiveness of the concept and led to the final design and implementation of the pilot field bridge.
While both bonded VHB™ Tape and structural silicone specimens exhibited some voids, there was less sensitivity of time to failure to the voids and defects seen in the VHB™ Tape specimens tested and significantly less scatter in the time to failure data than specimens made with the structural silicones.
In order to establish the influence of the behaviour of the specimens' structural properties in deformation and annealing on the value of σ В, we have analysed how their thermopower (E T) varies in rolling and thermal treatment.
It is also known that when performing mechanical testing of a tissue specimen, variations in the structural properties can be expected due to differences in dimensions of the tendon, temperature, and so on.
Afterwards, parametric studies on the extensive influence on mechanical performance were discussed by employing the specimens with structural defects in terms of the irregularity, under and over stretch states and adhesive failure.
During the tests, with increasing deformation of the specimens, different structural mechanisms developed subsequently, i.e. flexural action, compressive arch action (CAA) and catenary action.
A control specimen was prepared following the structural design of existing railway bridges in Japan.
A specimen was prepared following the structural design of existing railway bridges in Japan but without transverse reinforcements in the joint.
A DNA sequence corresponding to the HTLV-I regulatory gene tax was amplified from most cases (92% of thymomas, 93% of thymic hyperplasia specimens), whereas DNA corresponding to the structural gene pol was found in fewer tissues (75% of thymomas, 40% of thymic hyperplasia specimens).
