Fig. 3: Model discovery.
From: The mechanical and sensory signature of plant-based and animal meat
Discovered one-term models, on the diagonal, and two-term models, off-diagonal, for tofurky, plant sausage, spam turkey, animal sausage, animal hotdog, plant hotdog, extrafirm tofu, and firm tofu. All models are made up of eight functional building blocks: linear, exponential linear, quadratic, and exponential quadratic terms of the first and second strain invariants I1 and I2. The color code indicates the quality of fit to the tension, compression, and shear data from Table 2, ranging from dark blue, best fit, to dark red, worst fit.
