Atomic Packing Factor of FCC Solution

STEP 0: Pre-Calculation Summary

Formula Used

Atomic Packing Factor = (4*Volume of Each Particle)/(Volume of Unit Cell)
APF = (4*V_particle)/(V_{unit cell})
This formula uses 3 Variables

Variables Used

Atomic Packing Factor - Atomic Packing Factor is the fraction of volume in a crystal structure that is occupied by constituent particles.
Volume of Each Particle - (Measured in Cubic Meter) - Volume of each particle is the volume of each particle in unit cell.
Volume of Unit Cell - (Measured in Cubic Meter) - Volume of Unit Cell is is defined as the space occupied within the boundaries of unit cell.

STEP 1: Convert Input(s) to Base Unit

Volume of Each Particle: 10 Cubic Angstrom --> 1E-29 Cubic Meter (Check conversion here)
Volume of Unit Cell: 105 Cubic Angstrom --> 1.05E-28 Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

APF = (4*V_particle)/(V_{unit cell}) --> (4*1E-29)/(1.05E-28)

Evaluating ... ...

What is the physical significance of Atomic Packing Factor?

Packing factor indicates how closely atoms are packed in a unit cell and is given by the ratio of volume of atoms in the unit cell and volume of the unit cell. In atomic systems, by convention, the packing factor is determined by assuming that atoms are rigid spheres. The radius of the spheres is taken to be the maximal value such that the atoms do not overlap.
A slip plane with the highest atomic density is preferred for deformation because the distance between atoms are so small that dislocation movement due to lower applied stress is easier and higher atomic packing factor is an indication of ease of deformation.

How to Calculate Atomic Packing Factor of FCC?

Atomic Packing Factor of FCC calculator uses Atomic Packing Factor = (4*Volume of Each Particle)/(Volume of Unit Cell) to calculate the Atomic Packing Factor, The Atomic Packing Factor of FCC is the fraction of volume in a face centered crystal that is occupied by constituent particles.
