In general, ECAs are conducted electrically by the mechanical contact between the conductive particles and the bonding electrodes.
The material properties of resin and filler are listed in Table 1.
The contact angle of filler is taken as 35.4°, and Table 1: Material properties of resin and filler Densityρ [kg/m3] Viscosity, µ [Pa-s] Surface tension coefficient σ [ N/m] Resin 1200 0.38, 0.57, 0.19 0.45 Filler 7300 0.00181 0.45 (a) Initial state (b) µR = 0.57 at t = 6 ms Fig. 2 Simulation of filler coalescence (Vf = 45%).
Some larger particles through coalescence make even larger particles, whose size and behavior would be the main factors in ICAs applications.
In particular, it can be assured that resin viscosity is an important factor which can affect the coalescence characteristics.

The increasing amount of waste micronized powder adversely affects the shrinkage of the cement composite.
Using high-speed mills, the marble sludge was milled under the assumption that it will become more workable and its properties will be improved.
· The content of micronized marble powder in the mixture affects the porosity of the material.
Other parameters that have to be addressed are mechanical properties such as compressive strength, tensile strength, the elastic modulus and properties related to the reinforcement of elements, e.g. the matrix consistency with reinforcement.

Introduction Gear is one of the most important components of mechanical products.
The quality of its design and manufacture will affect its performance directly.
Many factors can impact the reliability of gears because of complex structures and changeable conditions.
The Strength Calculation of Cylindrical Gear Pairs In reliability analysis, the uncertainty in a system mainly comes from two aspects, which are statistical and non-statistical factors.
Variations of material properties and boundary conditions and errors in manufacturing and installation lead to randomness of physical and geometrical properties of the structure.

This especially affects the instruments with cutting edges made of hard tool alloys (HTA).
Physicomechanical properties influence the choice of machining modes [5] and the type of damage received by tool’s cutting edge.
It is known, that one of the primary factors that effects the efficiency of cutting tools is the change of HTA properties depending on the temperature of cutting [3,4].
In these studies as a criterion for determining the carbide blades’ maximum efficiency temperature, mechanical characteristic - stress intensity factor К1С, was used.

The field measurement is done at the laboratory Block E, Faculty of Mechanical and Manufacturing Engineering at Universiti Tun Hussein Onn Malaysia (UTHM).
Several factors such as the road surface, types of vehicles and speed will induce the wave propagation to the building [1].
Finite Element Modelling (FEM) Laboratory building E block at Faculty of Mechanical and Manufacturing Engineering (FKMP) is a two-storey building which is near to G3 block.
In ANSYS, every element is assigned with material constant to define structure properties in term of density, poison ratio and modulus of elasticity.

Introduction Low alloy steel represents one of the versatile engineering materials for a variety of structural applications due the advantages of its relatively low cost and attractive mechanical properties such as moderate yield strength, excellent ductility and high fracture toughness.
A survey of relevant literatures suggests that microstructures and consequent properties of the TIG-alloyed surfaces largely depend on some process parameters.
The L16 OA chosen in this study is a modified Taguchi array that can accommodate up to five factors at four levels.
The individual effects of all the factors are studied on the response variable.
However, the aim of the analysis is to identify the levels of the combining factors which present maximum surface hardness.
