Nevertheless, in those works, limited or no attention was generally paid to the crucial issue of the spatial variability of material properties within AM, which can produce critical forms of mechanical response and premature failure.
Table 1: Mechanical properties of adobe block and mud mortar (bracketed values indicate CoV).
More detailed description of the production process and physical properties of AM components can be found in [19].
By assuming a significance level p = 0.05, the F-factor was compared to the test F*-factor reported in the from Fisher’s table.
Recorded experimental responses of wallets was affected by large dispersion.

In Italy timber and wood products are becoming increasingly used for building constructions due to their excellent physics and mechanical properties.
Physical and morphological properties (density, knots, clusters knot, resin pockets, deviation of the grain, annual ring width position of board respect to the pith, humidity, etc.) along with mechanical and non destructive properties (elastic modulus, tensile strength, sonic pulse velocity) have been checked.
Regression analysis Timber’s strength can be predicted by measurements of properties that have a clear effect on strength itself, or, on those measurable properties that do not directly affect strength but are good indicators of it.

Irregular tubes maybe affect by temperature and other factors.
By virtue of their curved graphite structure, small diameter, high aspect ratio, and electronic structure, they possess many appealing properties.
These methods are mature, and have gained high properties CNTs.
The asterisk marked tubes are quite irregular, and their synthesis maybe affect by pulsatile flame and other factors.

The development of mine rescue robot for inspection is of great significance to improve coal mine production safety and reduce the loss of state property and people's life.
By formula (1) and (2), it can be obtained that the height of the obstacle, the length of the articulated arm, the center of the articulated arm’s gravity place, the length of the robot’s body, the center of the body’s gravity place, the radius of the driving wheel, the driving torque of the articulated arm and the properties of the contact surface are all related to the first step.
Length changes in articulated arm of these factors affect the first step the most complexly.
As the other factors remain unchanged, the driving torque of the articulated arm is provided M, the approximations are:
By the formula (4) and (5) it can be seen that the center of gravity position of the robot and the radius of the main track wheels are the main factors affecting the obstacle crossing.

The addition of fillers and pigments to silicone has been done to improve its physical and mechanical properties while maintaining its biocompatibility.
Maxillofacial prosthesis materials have continuously developed to improve its physical and mechanical properties.
The mechanical properties of silicone depend on three main factors such as molecular weight, degree of cross-linking, and content of fillers and pigments.
The properties of experimental silicones reinforced with silica fillers for dentistry.
Nanoenginered silica: properties, applications, and toxicity.

Based on these factors accurately simulated, the state transformation is simulated by setting the value of the thermal strain changes with temperature.
As a result, the state of stress is changed by the mechanical operation for removing surface oxide and splashing.
Thermal physical properties and mechanical properties of the material parameters reference Eurocode 3 standard [6].
So it is assumed that the entire heat affected zone has the same phase transition process.
When the element temperature reaches the transition temperature range, the material of the element is replaced by the material whose properties is able to represent the phase transition process impending.

To improve the mechanical properties, PCL has been blended or copolymerized with other polymers [8].
Materials Properties Like many other biopolymers, PCL did not have the mechanical properties to be applied in high load bearing applications which currently limit their use.
The addition of carbon nanotubes to PCL can enhance gas barrier properties of PCL as well as other properties such as the conductivity, thermal, mechanical [23].
Moreover, several nanostructures can be useful to provide active and/or smart properties to food packaging systems, as exemplified by antimicrobial properties, oxygen scavenging ability, enzyme immobilization, or indication of the degree of exposure to some detrimental factors such as inadequate temperatures or oxygen levels.

All composites were characterized both microstructures analysis and mechanical properties include tensile strength and hardness.
Porosity affect the mechanical properties, ductility and the strength of the cast product decreases.
This must avoided from composite materials, because it reduces the mechanical properties of composites [7].
The effect of graphite and magnesium addition on ADC-12 matrix to the mechanical properties are studied.
