"stretching direction" is correct and can be used in written English.
It refers to the direction in which something is being stretched or extended. Example: The yoga instructor instructed us to focus on our stretching direction, stretching our arms towards the ceiling before bending forward.
Particularly, the maximum electrical and magnetic properties in both the directions parallel and perpendicular to the stretching direction were obtained at the elastic limit stress level for the stretched nanocomposite films.
Height ranges ( m) Stretching direction Transverse direction Height direction .
Stretching direction and polarizations are shown in the insets.
For different stretching direction values, the depocentre geometry varies from strongly asymmetric to symmetric when the stretching direction corresponds to the bisecting line of the two VD segments.
The micro-phase separated PVAc nanodomains are aligned parallel to the stretching direction, whereas the crystallized PLLA lamellae are oriented perpendicular to the stretching direction (crystal c-axis along the stretching direction).
The mechanical properties of the oriented iPS/PPO blends were measured not only in the stretching direction but also perpendicular to the stretching direction.
Magnetic susceptibility measurements performed in three perpendicular directions of magnetic field confirmed the alignment in the stretching direction.
To control negative diffusion in the stretching directions, a Lagrangian method is used.
Cracks occur parallel to the stretching directions due to the anisotropic mechanical stretching of the PDMS substrate (Fig. 2A) in combination with the mechanical mismatch of the glassy top layer and substrate.
A biaxial stretching of PET and PEN resulted in a lowering of a vertical to the stretched direction.
Crystalline lamellae were seen in fibrils with their axis parallel to the stretched direction.
