Explicit Dynamic Analysis

Robust and durable designs are critical in the engineering world. Conventional analysis methods may be insufficient, especially for structures subjected to high-speed impacts, explosions or sudden loading. In such cases, exploratory dynamic analysis comes into play.

What is Explicit Dynamic Analysis?

Explicit dynamic analysis is an analysis method that examines the time-dependent behavior of structures using the finite element method. Unlike traditional static and implicit dynamic analysis, this method is ideal for modeling sudden events that occur in very short time intervals (e.g. milliseconds or microseconds) and their impact on structures.

Use Cases of Explicit Dynamic Analysis:

Vehicle Crashes: The effects of impacts on the vehicle body and passengers in car accidents can be modeled with excipient dynamic analysis to develop safer vehicle designs.
Sheet Metal Forming: The stresses and deformations that the metal is exposed to during sheet metal forming processes such as pressing, bending and drawing can be predicted in advance with these analyzes and faulty production can be avoided.
Effects of Explosions on Structures: Explosive dynamic analysis can be used to determine how resistant buildings and other structures are to explosions. In this way, more robust and safer structures can be designed.
Other: Explicit dynamic analysis can be used in many areas such as ballistic effects, dynamic behavior of machine parts, rockfall.

Advantages of Explicit Dynamic Analysis:

Suitable for Modeling Sudden Events: It is ideal for modeling events that occur in short time intervals and their effects on structures.
Can Handle Complex Geometries: Can be applied to structures with complex geometries.
Produces Realistic Results: It produces realistic results by simulating real-world events quite well.

Disadvantages of Explicit Dynamic Analysis:

Computation Intensive: Requires more computational power compared to traditional analysis methods.
Long Solution Time: For complex problems, the solution time can be quite long.
Requires Expertise: Special expertise and know-how are required to perform these analyses correctly.
