Crack Free: Superposition Benchmark

A leading aerospace manufacturer applied superposition benchmarking to Inconel 718. Standard single-stress benchmarks predicted a safe operating window. However, the superposition benchmark (thermal + phase + rotational stress) showed a 120 MPa spike at the disc bore.

Result: By redesigning the pre-weld heat treatment to superimpose a compressive phase field, the net stress dropped to 85% of the yield strength. Crack-free production yield rose from 62% to 98.5%.

This is the most critical factor. A "crack" is an executable file from an untrusted source. Attackers often hide crypto miners, keyloggers, or ransomware inside benchmark cracks. A crack free approach ensures you are downloading a digitally signed binary directly from Unigine’s servers. superposition benchmark crack free

On HWBOT and 3DMark’s Hall of Fame, a "Crack Free" submission is the only submission that counts. If you upload a score with a single white pixel artifact, moderators will reject it.

To compete for world records (e.g., RTX 4090 Superposition 4K Optimized > 24,000 points), you must run extreme LN2 cooling. But here is the paradox: On liquid nitrogen, GPUs crack constantly due to the cold bug. Pro overclockers use a technique called "Artifact Scanning" —using AI to visually detect cracks during the run and dynamically throttle the memory clock in real-time.

For air and water coolers, the "Crack Free" score is the true measure of a daily-driver overclock.

For a linear elastic material with small deformations and a known initial residual stress field $\sigma_res(x)$, the total stress under an additional service load $\sigma_load(x)$ is: A "crack" is an executable file from an untrusted source

$$ \sigma_total(x) = \sigma_res(x) + \sigma_load(x) $$

If the material is crack-free at $t=0$, the condition for no crack initiation is:

$$ \max_x \in \Omega f(\sigma_total(x)) \leq \sigma_crit $$

where $f$ is a fracture criterion (e.g., maximum principal stress, von Mises with hydrostatic cutoff, or a stress-intensity factor $K_I$ for a virtual crack nucleus).
