Properties of Materials Name: Institution: Tutor: Subject: Date: Task I Density This is the mass per unit volume of a material or it can be defined also as the mass of a substance divided by its volume. Examples of density of materials are: 4-6 titanium weighs 0.610 pounds per cubic inch; 6061 aluminum weighs 0.098 pounds per cubic inch; 4130 steel weighs 0.283 pounds per cubic inch…

Introduction

Stress and strain Stress has been described as the amount of force applied to a certain material divided by the cross sectional area of the material to the direction of the force. Strain properties, on the other hand, indicate how much a material lengthens under stress. This is measured by dividing the distance the materials over its original length. Below is a typical diagram of a stress-strain curve for different materials. The Figure below denotes the stress-strain curve for steel under different measures of stress: Figure 2: From the above diagram, we can deduce that strain increases faster than stress at any one point beyond point A. Below this point, any steel specimen whether loaded or unloaded would easily return to its original length, which is described as elastic behaviour. Beyond point B, any additional stress results into deformation or inelasticity (George et al, 2002, 26). Tensile and comprehensive strength The strength of a material can be measured by putting a material sample in a powerful materials testing machine, which pulls the materials apart and then records the force required to do so, plus the deformation to the material. Compression strength is determined by subjecting the material under pressure until it breaks i.e. heat, impact, et cetera. ...

Characterisation material physical properties of porous materials
According to this theory, three different kinds of waves propagate within the porous material. One is the compression wave propagating in the fluid phase, the second is the compression wave travelling in the solid phase, and the third is the shear wave propagating in the solid phase (Pan & Jackson). The Biot model for predicting sound propagation in porous materials is based on five material…
Materials and Corrosion
Crevice Corrosion Corrosion occurring within or adjacent to crevices, which are commonly left at joints, due to small volumes of stagnant corroding fluids is known as crevice corrosion. The most important feature of this type of corrosion is the contact with stagnant solution which takes place in interstices, near seals and in cervices made for nuts and rivet heads. The metals and alloys used in…

According to a survey that was carried out by our firm, we realized that many instances windows were severely damaged. Upon keenly studying the damages, it was realized that it was partly due to environmental factors and partly due to poor maintenance. The damages on the widows caused variations in geometric configuration, composition, porosity and adherence of corrosion products. They also cause…

Quality assurance plays an active role in materials testing. Quality assurance carries out calibration test and manufacturing test. Calibration test is carried out to determine the workability of the measuring properties. Manufacturing test is carried out to determine the adherence to standardization. Some of the tests through which engineering materials are subjected to can be categorized as…

There are two categories of landing distance; the actual landing distance, and the required landing distance. The actual landing distance is the total distance taken in landing and completely stopping after crossing the run way thresh hold at 50 ft (Civil Aviation Authority of New Zealand 2011). Required landing distance is the distance taken after a factor is applied to the actual landing…
