Moreover the thermal damage due to the low thermal conductivity properties of the PLA material also affects the contact zone die-sheet.
The temperature reached by the sheet during the thermoforming process has an influence on the final quality of the manufactured products, affecting both the mould and the thermoformed sheet.
Nonetheless, PLA material shows good frictional properties since the differences stablished in this work in the top surface of the die are less than 1mm after being exposed to consecutive low number of thermoforming cycles (around 25).

Each type of sand is used in a certain area, in which it will be able to show its properties to the maximum: buoyancy, flowability, porosity and moisture capacity.
In the sand dewatering industry, various mechanical methods and means of sand dewatering have become exceptionally widespread, the use of which is simultaneously considered an integral part of the complex solution to the problem of preventing materials from freezing and preserving their free-flowing properties.

So far, zirconia-toughened ceramics are replacing alumina because of their outstanding mechanical properties leading to high reliability in ceramic components.
A non-exhaustive synthesis of the present applications of bioinert ceramics in medical devices and of their mechanical properties are is illustrated in the following Tables 1 and 2.
The metastability of the tetragonal phase is the key of the interesting mechanical properties of zirconia, but is also the origin of its main drawback, e.g. the spontaneous transformation of the metastable tetragonal phase into monoclinic [19].

Then, the resulted films were characterized on their optical, structural, and photovoltaic properties.
Therefore, in the detailed study, we investigated the effect of those layers on the optical, structural, and photovoltaic properties of BiOI films.
Due to the covalent bond in all atoms, BiOI has good optical and mechanical properties.
We assumed that the insertion of TiOx and TiO2 might affect the shunt resistance value (Rsh) and it had an impact on the open-circuit voltage enhancement.

Introduction When the actual equipment test, due to the random factors of the inherent factors in the product, manufacturing, assembly and the natural environment, each test result is different.
However, the existing virtual prototyping of equipment is analyzed under the certain factors, neither taking the size of manufacturing and assembly, and the discrete structural properties into account, nor considering the randomn of the input load.
So considering the impact of random factors can reflect the true nature characteristics of the equipment, when in the virtual test of the equipment.
Shooting process in the bore is affected by many random factors, not only there is the random interference in the firing process environment, but also in the powder itself.

To investigate these factors influencing the wrinkling initiation experimentally, a modified and the requirements customized test form based on a simple test geometry, the so called Yoshida buckling test, is created.
Furthermore functional properties as insufficient mechanical strength or lack of corrosion properties due to material overlap are negative effects of winkles.
However, to be able to apply this testing procedure to technical relevant curvature and sheet thickness ranges, an adjustment of process and sample geometry to the specific properties of the test setup is necessary.
Here, in particular, the friction and the radius of the punch are the major impact factors.

(2) Therefore, the cutting thickness e is an important factor affecting the cutting load.
The sample is able to come into the core institutions as much as possible on the condition that the sample to maintain the original form (to maintain the solid features) does not decompose under the influence of centrifugal force (fluid properties enhanced).
Ignoring friction of the support tube and soil cylinder, the mechanical model of the sampling process is as shown below:

This finding will benefit the coring drill control in the lunar soil with similar properties.

Introduction The failures of metal parts in industries like metallurgy, mining, electric power, cement areas mainly result from wearing, corrosion, oxidizing at high temperature and some parts suffer from dual effects of wearing and high temperature, which require not only enough hard phases for wearing resistance but also excellent mechanical properties and oxidizing resistance.
The effects of particles volume fraction, coating for particle and particle size on the high temperature wearing resistance for Al2O3/heat-resistance steel matrix composite material and high temperature crack behavior under different conditions were analyzed while provided effective data and experience for the composites with excellent comprehensive properties on both theory and practice.
Metal matrix with high strength sustains ceramic particles effectively for improving integer wear resistance property as forces transmission between the particles and the matrix during the working period for the composite material with required temperature comprehensive properties, while ZG40Cr25Ni20 alloy was choose as metal matrix material in the experiment with the same chemical composite and mechanical properties as the HK alloy [2].

In the factors that influence hot pressing process, pressure, temperature and time span occupy a leading position.
The pressure (mostly water vapour pressure) plays an important role in stress relaxation phase which directly affects whether the sheet is getting layered or blistered thus affects the mechanical properties and heat-transfer interaction.
