Differences between displacement obtained by analytical and numerical calculation are <1% for straight beam and 8.6% for curved beam.
As the displacement field of the beam element in iFEM is constructed based on an isotropic straight beam structure, whose cross section is invariable along the whole beam, the deformation of the tapered beam cannot be estimated.
Nevertheless, due to the smaller temperature-induced deflection making the test beam in this study close to a straight beam, the shear stiffness of bearing has little influence on natural frequencies of beam.
It improves inspections on straight beam applications, such as composites and pipeline corrosion mapping, as well as angled beam inspections for weld and TOFD.
The flexural strengths of GPC straight beam and L-beam were 1.50 times and 1.52 times greater than CC.
Eight equal straight beam elements were used to approximate the curved beam.
GE Measurement & Control (Germany) has introduced the MB.FPA16 and B.FPA16 ultrasonic probes, the world's first straight beam phased array probes to feature hard face, direct contact surfaces instead of nonabrasive protective membranes.
The agreement between the numerical and experimental results is excellent for the thin straight beam in bending even with a model which is not taking in account shear [12].
In Figure 1, asthe displacement of the proof mass in the drive direction is x, the deformation of the straight beam in Beams 3 is x/2.
The secret to the speed lies in how the researchers manipulated the laser signal to form an optical vortex (also known as an orbital angular momentum carrying-beam, or OAM beam), where the light moves in a spiral, rather than a straight beam akin to a laser pointer.
A red laser has also been mounted under the minute hand that projects a straight beam of light on to the adjacent hour mark.
If a straight beam is supported at any two points, internal stresses in the beam develop due to self (gravity)-loading.
