Compared to un-perforated specimens, perforations reduce elastic stiffness and yield strength.
This underestimated area could overestimate both hardness and reduced elastic modulus, with a more significant effect on hardness [37].
The deposition rate, nitrogen content, hardness and reduced elastic modulus decreased with increasing nitrogen flow rate.
For example, by reducing elastic modulus of piers by 30%%, the first natural frequency of the bridge was decreased about 25%%.
The presence of increased smooth muscle, lymphocytes and ducts (not associated with prostatitis) and reduced elastic tissue characterises stromal BPH at histopathology.
The reduced elastic modulus, Er, can be calculated from the following equation: 1 E r = 1 − v film 2 E film + 1 − v i 2 E i (3).
In this way, the hardness (H) and reduced elastic modulus (E r) as a function of penetration depth are determined for a single loading/unloading cycle [18].
Additionally, its influence on the resulting mechanical properties including hardness (H), reduced elastic modulus (Er), elastic recovery and wear resistance of the alloys was evaluated using nanoindentation.
The hardness (H) and the reduced elastic modulus (E*) of (Cr0.5Al0.5 1 − xSixN coatings were acquired by a nanoindentation.
The mechanical properties of the coatings, in terms of hardness and reduced elastic modulus, were determined by nanoindentation technique.
