Verification and Validation (V&V) of Uniaxial Tensile Test Simulation Results of Composite Materials: Fusion of Actual Measurement and Homogenization Analysis

Use of Carbon Fiber Reinforced Plastic (CFRP) and other composite materials in transportation equipment, beginning with automobiles, has begun in response to calls for weight reduction to reduce environmental impacts. Structural analysis simulation techniques such as CAE (Computer Aided Engineering) are widely used in design development of transportation equipment. In conventional development, there was a time when a design was considered complete with only CAE analysis. Today, however, actual measurement under the same conditions as the CAE analysis model and verification by comparison with the CAE analysis results to validate appropriateness of the simulation results (V&V: Verification and Validation) is considered important, and product design utilizing both actual measurement and CAE analysis is becoming a general social requirement. This article introduces examples of V&V through a comparison of the CAE analysis results and actual measurements of Carbon Fiber Reinforced Thermo Plastic (CFRTP) fabric material, which had been difficult to analyze because it is an anisotropic material.
