Laser metal deposition (LMD) industrial use demands research about the influence of the parameters in the built parts density, accuracy and mechanical properties.
Introduction Nowadays laser metal deposition (LMD) in industries demands research on the influence of the parameters in the built full density, accuracy, and mechanical properties.
Especially for the thin-wall parts, knowledge about the correlations between processing parameters and the final result is indispensable.[3], [4] This study explores the relation between the process parameter affecting the quality and properties of a series of AISI3016L stainless steel thin-walled parts produced by LMD.

However, the materials have various mechanical, thermal properties, and varied volume, which produced severe stress concentration.
These above literatures show that the interfacial bonding is very important to the sensing properties and residual stress, which were influenced by various factors.
Thus, due to the mechanical properties' mismatch between embedded sensor and host structure, when loading is applied on the structure along the sensor's longitudinal direction, lateral mechanical response of the structure may induce further local stress on embedded FBG sensor, and hence may induce the interfacial debonding.
Therefore, based on the above analysis, the embedded sensor does not affect the mechanical properties of HFRP.
Upon simulation data analysis, on can conclude that: Due to mechanical properties mismatch between FBG and host structure, particularly their elastic modulus, embedded sensor did experience additional stress field when load was applied along sensor direction; and the more the mismatch exists, the more the additional stress field is induced.

All of these historical pagodas were registered and
protected as the important cultural properties by Japanese Government.
Sezawa,K. and Kanai,K. (1936) studied theoretically their anti-seismic properties by employing elastic wave propagation model, as shown in Fig.3.
Even if one of those functions happens to be lost, the other inherent anti-seismic factors would cover it, therefore, the structure would still safe against large earthquakes.

And he studied the mechanical properties, biocompatibility and cutting performance of zirconium biscuit in the semi-sintered state.
Mechanical properties of materials mainly relates to the strength and hardness.
During the machining process of ceramic material, edge chipping is a common phenomenon, and which is one of the key factors deciding the qualities of ceramic denture.
Materials used for denture restoration should own good mechanical properties, biocompatibilities and machining properties.

The factors involved in the process are punch radius, die radius, die gap, punch travel and punch velocity.
The aim of this paper is to investigate the factors that affect the springback behavior of stainless steel in air V-bending using Finite Element Method (FEM) software Simufact-FormingTM version and material database MatILDa.
The amount of springback influence identifies by many factors such as tool shape and dimension like punch and die radius, die gap, punch travel, bending force and sheet thickness.
The mechanical properties of the stainless steel 304 by a uniaxial tensile test are shown in Table 2.

The influence of these factors on the fatigue behavior of spot welded joints made of AHSS has not been sufficiently taken into account.
As a simplification, equal mechanical properties were assumed for the fusion zone and the HAZ.
Nugget diameter and sheet thickness, as the usually suspected influencing factors, were kept constant during the investigations.

This is mainly caused by the lack of data in order to evaluate the process economically and differentiate it to other processes like arc and laser welding, also regarding technological factors.
Moreover, the absence of a liquid phase during the process leads to favourable seam properties, like enhanced fatigue properties [4-5] and formability [6].
In this way, FSW seams can exhibit outstanding mechanical properties.
For the referencing experiments, welds were produced with a conventional aspect ratio of the tool and the rotational speed was varied in order to display the effects on the resultant spindle torque, mechanical properties and seam appearance.

Metamaterials are controlled arrangements of material structures in which their mechanical properties can be tailored by tuning their geometrical parameters.
These apparent properties are a function of the metamaterial topology and volume fraction [4].
Apparent mechanical properties of cellular solids are usually calculated from static simulations or experiments, including standard tensile, compression and bending tests.
Few works focus on the characterization of the mechanical properties of lattice-beams subjected to different loading conditions, which is the purpose of this work.
Then, the metamaterial synthesis approach used here enables the generation of beams with mechanical properties adjustable to a desired value.

Several SMA devices are based on their unique properties.
Even though they possess high damping and attractive shape memory properties they are difficult to produce and process and are also more expensive.
DMA is a technique that can be used to obtain a lot of information pertaining to the damping/mechanical properties of any viscoelastic material.
Other factors which influence the strain recovery by SME are the imperfections in the material, such as quenched-in vacancies, dislocations, etc., which cause the pinning of martensite plates, and thereby hampering the transformation which, in turn, decreases the strain recovery.

Regarding heat treatment influences on mechanical properties of TWIP steels, in this paper we discuss twinning phenomenon resulting from this kind of treatment.
Although presence of coherent interfaces inside poly crystal materials including twin boundaries have significant influence on mechanical properties of metals and alloy steels there are however, no sufficient qualitative studies on the impacts of twin boundaries on the mechanical properties of steels [2].
Some important factors affect the rate of twins formation during grain growth including: rate of deformation before annealing, temperature and time cycle of annealing heat treatment, grain size, energy of grain boundaries, migration velocity of grain boundaries, SFE, context of grains and impurities [4].
So, it is expected that annealing twins have a significant influence on mechanical properties of materials following Hall-Petch equation [8].
