# The Characteristics of Solids and How to Create Good Code According to SOLID Design Principles

This article will discuss the main characteristics of solids and how to create good code according to SOLID design principles. Besides, the principles are also widely used by engineers. Hence, they are essential for a good program to be developed. They also meet industry standards. To develop good code, adhere to the principles mentioned below. Let’s look at them in detail. You can also learn about other principles of good code development. The following are some of the common ones:

## Crystalline solids exhibit anisotropy

Anisotropy is the characteristic of crystalline solids which shows differences in physical properties along different directions. This is the result of different arrangements of the particles in the solid’s unit cells. While amorphous solids do not have any crystals, they are still crystalline solids. The symmetry of the unit cell determines the level of anisotropy. In the same way, different atomic arrangements in the same direction cause different physical properties.

## Amorphous solids exhibit cleavage

There are two types of solid matter: crystalline and amorphous. Crystallized solids exhibit cleavage planes, which are the weakest points of the crystal structure. When they are cut, they form two smooth parts. Amorphous solids, on the other hand, do not exhibit cleavage planes. These solids are often not reused in industrial processes because they are unstable and easily broken.

## Amorphous solids have no lattice pattern

Amorphous solids do not have a specific crystalline structure. Their molecules are made up entirely of covalent bonds. Amorphous solids have no specific melting point. They melt at a variety of temperatures, and thus, are classified as pseudosolids. Amorphous solids are not crystalline, but exhibit all the properties of solids. As such, they are often called glass or liquid.

## They have no melting point

What exactly is a solid? A solid is a crystalline collection of atoms, ions, and molecules that are packed together in three dimensions. The atoms in a solid are referred to as lattice points, and these atoms are typically visualized as round spheres. The resulting solid is a closed-packed array. Unlike liquids, solids can never melt or expand, and therefore, have no melting point.

## They have a fixed volume

A solid is a type of material with a fixed shape and a fixed volume. It has tightly packed particles. These particles are kept in place by other particles in the material, and cannot move outside of the solid. In addition, solids do not flow. This characteristic is what gives solids their fixed shape. The properties of solids are dependent on their volume and shape.
