What is a mass module?
materials can generally be compressed when they are subjected to external pressures applied to their surfaces. Reducing the volume of material under the pressure varies greatly from material to material. The gases are generally the easiest to be compressed under pressure, while solids can be compressed relatively little and with great difficulty. The mass module is a material property indicating the degree of material resistance to compression. It can also be referred to a number of other terms such as a mass module of elasticity, compression module and more. The high mass module for the material indicates a relatively high resistance to compression, which means it is difficult to compress. The low value indicates relatively low compression resistance, which means that the material is relatively easily compressed. For example, a mass module of steel is several orders of magnitude larger than the air to be compressed relatively easily with the air compressor. As the material warms, its volume generally expands, leading to a more open physical structure thatOU is easier to compress. The air captured in the material also affects the physical structure of the material that affects its mass module.
Some fluids, such as water or hydraulic fluid, are sometimes denoted as non -pressure fluids. This is not strictly accurate, but because their compression is relatively low, it may be ignored in some engineering calculations. In certain circumstances, however, in some high -pressure situations, for example, take into account to ensure the correct design and function of the system.
For example, the power of the hydraulic device under very high pressure can be degraded unless the mass module of hydraulic fluid is taken into account when designing the system. This is because some energy is spent on the compression of hydraulic fluid rather than aiming directly towards the work of the device. The fluid in the system must be compressed to tThe extent that it resists further compression before the device and load are loaded. Due energy from the primary task may affect the position of the device, the power supply available for the intended function, response time, etc.
The bulk module is less often a characteristic of interest in solids, because it is usually difficult to compress, but under certain circumstances is relevant. The speed at which the sound passes through a solid substance partly depends on the volume module of the material. The amount of energy that can be stored in a solid is also related to this feature, so that the earthquake and seismic waves are relevant.
As a mathematical function, this material property is expressed as the ratio of the applied pressure to change the volume of the substance per unit of volume. This provides a value expressed in the same units used to express the pressure, as the volume units are canceled. In graphical form it is the slope of the curve created by plotting the pressure applied to the versus material correspondingSpecific volumes of material at these pressures.
