Method and device for establishing HBPRC constitutive model

Abstract

The invention provides a method and device for establishing an HBPRC constitutive model, and relates to the technical field of civil engineering. The method comprises the following steps: establishing a first calculation relationship among nominal stress, mechanical damage variables, elastic modulus and axial strain of HBPRC according to a damage mechanics theory and a strain coordination principle; obtaining a second calculation relationship among the mechanical damage variable, the axial strain, the dimension parameter of the Weber distribution and the shape parameter of the HBPRC; obtaining a third calculation relationship among the enhancement effect parameter, the reference elastic modulus and the elastic modulus of the HBPRC according to the effects of the BF and the PF. According to the first calculation relation, the second calculation relation and the third calculation relation, an HBPRC constitutive model is established, the constitutive model is the calculation relation between the nominal stress of the HBPRC and the reference elastic modulus, the axial strain and the total damage variable, and the total damage variable is obtained by calculating the mechanical damage variable and the enhancement effect parameter. The method is used for establishing a constitutive model of HBPRC.

AI Technical Summary

Benefits of technology

The inventors have developed methods for creating models that can accurately predict how much force or deformation it will cause damaging changes on materials like cement blocks used during construction work. These models are based upon specific physical properties such as Young’s Moduli (modes) and tensile strength values from various sources. They also include relationships among these quantities along different directions which help them better calculate material behavior under loadings. Overall, this technology allows researchers to make informed decisions about designing structures made up entirely of strong materials while reducing their risk of failure due to environmental factors.

Problems solved by technology

This patented technical problem addressed by this patents relates to developing new types of polymer composites called basalfiber or polyproplyene fiberglass composite(BF/PC). These compositions offer advantages such as improved strength without adding more metal compared to traditional methods like iron bolts, while still maintaining their high resistance against environmental factors including salt water damage. Additionally, these compositons provide excellent flexibility and impact resistant qualities even at extreme temperatures.
