This study introduces a new method for simulating brittle material fracture by treating objects as infinitely stiff rigid bodies. It proposes a time-averaged stress criterion and novel collision handling for accurate simulation of fractured objects.

Area of Science:

  • Computational physics
  • Material science
  • Computer graphics

Background:

  • Simulating fracture in brittle materials is computationally intensive.
  • Explicit and implicit methods face challenges with time steps and nonlinear systems.
  • Existing stress criteria can lead to inaccurate fracture predictions, especially for stiff materials.

Purpose of the Study:

  • To develop a computationally efficient and robust method for simulating the fracture and denting of brittle materials.
  • To address the limitations of traditional stress criteria in fracture simulation.
  • To introduce a novel collision handling technique for fractured rigid bodies and thin shells.

Main Methods:

  • Treating materials as infinitely stiff rigid bodies to bypass computational burdens.
