When a large force is being applied to the particles, deformation becomes irreversible. The applied force will cause the particles to change shape leading to void spaces being filled. Examples of excipients which are known to undergo plastic deformation when a force is applied to them include microcrystalline celluose and LHPC.

What happens to a material during ductile deformation?
During ductile deformation, a material undergoes plastic deformation, meaning it permanently changes shape without breaking. This results in the material stretching and elongating before eventually yielding and forming necks or thin regions. The material exhibits a higher degree of deformation before fracture compared to brittle materials.
What is plastic deformation?
Plastic deformation is a permanent unrecoverable deformation. When the load that caused the deformation is removed, the material will not return to it's original shape but will maintain it's newly deformed shape.
What is flow stress?
flow stress is yield stress of material during plastic deformation
What happens during elastic deformation for drugs?
Elastic deformation occurs when an opposing force is applied to the drug after particle rearrangement (i.e. the initial repacking of the particles). If the force is released before the yield point is reached, the particles of the drug will return to their original shape. However, if the force goes beyond the yield point, the powder will undergo plastic deformation or brittle fracture.
What happens if someone lies about you during your security clearance investigation?
You can sue them for deformation of character. It is also another crime.
During metamorphism the material undergoing deformation remains a solid?
During metamorphism, solid rocks are subjected to high temperature and pressure conditions, causing them to recrystallize and change mineralogy without melting. The material undergoes deformation through solid-state processes, such as plastic deformation and grain rotation, while maintaining its solid state.
What happens during brittle fracture for the excipients of drugs?
The articles will break and fracture when a force is applied to them. These broken up particles will fill up void spaces, creating a larger surface area with new contact points. These new contact points will lead to a strengthened surface. Excipients which are known to undergo brittle fracture include lactose and Ca phosphate.
What happens to the energy in a collision between objects?
During a collision between objects, the energy is transferred and can be transformed into different forms, such as kinetic energy, heat, sound, or deformation of the objects involved.
Does deformation cause the ground to shake during an earthquake?
Yers.
Would you expect a crystalline ceramic material to strain harden at room temperature?
No, crystalline ceramic materials generally do not exhibit significant strain hardening at room temperature. Unlike metals, which can strengthen through dislocation movement and rearrangement during plastic deformation, ceramics typically have a strong, rigid structure that does not allow for such mechanisms. Instead, ceramics tend to be more brittle and may fracture rather than undergo plastic deformation or strain hardening.
What is the Significance of recrystallization temperature in metalworking?
Recrystallization temperature in metal working can be defined as the temperature at which the plastic deformation takes place perfectly. The stresses induced during the process is are grater than the yield strength and less than the fracture strength.
What is the process in which rocks change shape is called deformation deposition composition or flotation?
The process in which rocks change shape is called deformation. During deformation, rocks undergo changes in shape, volume, or orientation in response to stress. This can result in the formation of folds, faults, and other structural features in rocks.
