The nozzle position significantly affects the adhesive strength.
Because the stress distribution is in both of the adhesive layers, the adherends must be analyzed using their material properties [6].
The material properties are shown in Table 1.

The procedure to determine basic mechanical materials properties from the tensile test is specified for example in standards ASTM [7].
The basic mechanical properties of the investigated steel are also determined.
Increased accuracy determines mechanical properties of the material due to the fact that it does not require knowledge of the curvature radius of the neck contour R, and that for each incremental step solves the equations of equilibrium of the specimen.

The physico-mechanical properties of different types of steel and bamboo fibers were investigated.
Mechanical and physical tests were used to measure the retained properties and to observe the causes of damage and strength reduction.
Since degradation of FRP materials mainly depends on diffusion and chemical reactions, both of these factors can be accelerated by raising temperatures.
Measurements of various properties of FRP materials exposed to aqueous media showed the possibility of a sudden decrease, after a certain induction period, of the mechanical properties of composite materials upon exposure [1].
Some authors have studied the mechanical properties of lignocellulosic/polyester composites with well-defined fiber orientation (unidirectional or bidirectional) [3-6].
