Discontinuous Deformation Analysis
Discontinuous deformation analysis (DDA) is like playing with building blocks, but instead of making a regular structure, we make a jumbled up one with different shapes and sizes. We imagine that we live in a world made of many tiny blocks and we want to see how they move and interact with each other.
To do this, we divide our world into smaller sections called "blocks" or "elements." Each element is made up of many small pieces or facets that are connected to each other like puzzle pieces. We can imagine that these puzzle pieces can slide against each other, break apart or stick back together.
We also imagine that there are forces acting on these puzzle pieces. For example, if we push on a block, it will move and the pieces in the block will slide against each other until they reach a stable position.
We use computers to simulate all of these movements and forces. The computer breaks the blocks into tiny pieces and calculates how they interact with each other. We can see what happens when we apply different forces, like earthquakes or avalanches, to this jumbled up world.
DDA is useful in many areas, like understanding how buildings and bridges respond to earthquakes, or how rocks move and break during landslides. By breaking things down into smaller pieces and simulating their interactions, we can better understand how these systems behave in real life.
