For designers of functional surfaces, knowing when a material will initially fail under a worst-case application condition is a first step in understanding how to design and build better solutions. When using accelerated testing until a wear or erosion incubation period has passed, where damage is finally measurable, it provides quick statistical assessment of success against prior results. However, the challenge is to discover what properties of the material lead to the improvement.
By measuring the material properties at appropriate measurement scales and using this data in the simulation, one can find under what worst case impact scenarios the material will fail for a variety of different contact sizes.
With a quantified understanding of the various critical stress and strain fields generated; visibility and guidance on what properties need to be modified can lead to dramatically improved performance. Now this can be done for solid particle, water droplet or combinations of the two contact conditions to find worst case scenarios for your coating system design.
Key Benefits:
- Accelerate materials and process design with a focus on designing, measuring and validating mechanical properties improvements.
- Allow users to see at what critical contact condition a design solution will fail, or what type of stress field, distortion, strain etc. is the dominant failure mode and this helps inform the designer of the type of material properties needed.
- Materials data collected at appropriate measurement scales to inform realistic mechanical properties as the starting point in simulation, and for verification of design improvements.
- Simulate fluid droplet and/or solid particle impact
- Suitable for multi-layered materials design of any solid material and even for time-dependent viscoelastic polymers.
In this short thirty second animated simulation, a ductile material is impacted with later smaller impacts leading to critical loads near the outer rim of previous impact craters.
