Abstract: A novel lightweight, compact shock isolator utilizing composite disc springs was designed using an integrated numerical analysis methodology (Integrated Computational Materials Engineering, ICME). This methodology was used to rapidly screen conceptual designs by guiding material selection, disc geometries and assessment of margins-of-safety (MoS). Designs were optimized for various shock environments. Current polymer composite disc springs utilize low critical distortional matrix systems. This results in relatively low failure loads requiring stacking multiple discs to increase shock absorbance yielding undesired increases in weight, space and cost. In this study, increased shock absorption was realized by using a higher critical distortional matrix in combination with increased height/thickness ratios for the disc. This enabled a desired nonlinear "snap-through" behavior of the composite disc requiring non-linear analysis methods and incorporating non-linear contact algorithms. The automated ICME tool was used to generate a desired QZS (quasi-zero stiffness) response within the load-displacement curve for effective shock isolation and determined the required critical material properties of the constituents. A physics-based failure theory was used to determine MoS contour plots. Using the automated ICME tool significantly reduced the design cycle time resulting in testing for validation rather than testing to design. Numerical examples are provided to demonstrate the utility of the automated ICME tool for designing the innovative shock isolator.
