Is the Plastic trash can easily deformed when it is hit by external force?

In daily life and public environments, Plastic trash cans are inevitably hit by external forces, and whether they are easy to deform depends on multiple factors.

First, the material properties of Plastic trash cans have a key impact on their ability to resist impact deformation. If it is a trash can made of high-density polyethylene (HDPE), this material itself has a high density and good toughness. When it is hit by general external forces, such as being kicked accidentally or hit by a lightweight object, it can rely on its own molecular structure elasticity to rebound to a certain extent, and it is not easy to deform significantly. If it is a trash can made of polypropylene (PP), it has good rigidity and hardness, and can maintain a stable shape when facing a small external force, but it may be fractured and deformed due to lack of sufficient toughness under a large impact.

Secondly, the structural design of the trash can also largely determines its ability to resist impact deformation. From the overall shape, the circular Plastic trash can can disperse the force more evenly when it is hit by external forces from all directions. For example, when the side of a circular trash can is hit, the impact force will be dispersed along the circumference, and it is less likely to produce excessive deformation in a certain part than a square trash can. The corners of square trash cans are relatively weak areas. When hit by external forces, these corners are more likely to deform because stress is easily concentrated at these sharp angles.

In addition, the wall thickness of the trash can is also a factor that cannot be ignored. Plastic trash cans with thicker walls are like having a more solid "armor" and can withstand greater pressure without deformation when hit by external forces. Thick walls can provide more structural support for the trash can, so that the external force is dispersed over a larger area. On the contrary, when facing the same size of external force impact, thin-walled trash cans are more likely to dent or bend due to lack of sufficient material support.

In addition, the amount of garbage inside the trash can will also affect its ability to resist impact deformation. When the trash can is full of garbage, the garbage can can play a certain buffering role, partially absorb the impact force, reduce the pressure on the trash can itself, and thus reduce the possibility of deformation. However, if the garbage is unevenly distributed, it may aggravate the deformation of the trash can when it is hit, because uneven garbage will cause uneven stress distribution.

In summary, whether the plastic trash can is easily deformed when impacted by external force is the result of the combined effect of multiple factors.
