System that makes a prediction regarding a material, including: storing descriptors each describing a parameter regarding processing means, structure, property, or performance of the material; storing prediction models each describing an input and output relationship among the descriptors, wherein each prediction model inputs one of at least two of the processing means, structure, property, and performance, and outputs another one thereof; storing workflows each describing that at least two of the prediction models are connected via a descriptor, wherein the output of one prediction model is accepted as the input of another prediction model; giving an input to each of the workflows, executing the workflow including execution of each prediction model included in the workflow, and storing an execution result including an output result of each prediction model included in the workflow; managing execution results, workflows, prediction models, and descriptors in four hierarchical layers by assigning a unique identifier.

A method of evaluating impact force input to a workpiece member with a laser irradiated in laser peening processing is provided. This evaluation method includes a signal acquiring step, an input function calculating step, and an evaluating step. In the signal acquiring step, a detected waveform is acquired. The detected waveform is output during the laser peening processing by an AE sensor that detects an elastic wave generated in the workpiece member. In the input function calculating step, an input function I(t) by laser irradiation is calculated. In the evaluating step, impact force is evaluated using the input function I(t) by the laser irradiation.
