This study explores how composite materials, characterized by viscoelastic properties, can alter in real-time due to changes in their physico-chemical state influenced by external factors like temperature, humidity, solar radiation, dynamic loads over time, and resonance conditions. Various materials exhibit rheological phase changes, notably including anti-corrosive and film-forming paints in thick layers, bitumen, asphalt mixtures, specialized mortars, fixing and sealing putties for glazed surfaces, unique cements, and stabilized soils for road construction. It has been observed that during the use of construction works with composite materials undergoing rheological phase changes, the rheological behavior can shift from the Voigt-Kelvin (VOK) model to the Maxwell (MX) model and vice versa, especially in scenarios different from the designed conditions. These scenarios include the dynamic regime of structural vibrations and noise, solar radiation, dynamic effects from wind and intense precipitation, and the action of earthquakes. Understanding these factors is crucial for predicting the long-term performance and durability of composite materials in various environmental conditions. In this context, the study provides evidence from efforts to parametrically identify the resonance response of various materials with rheological phase changes under controlled vibrational conditions.

摘要

This study explores how composite materials, characterized by viscoelastic properties, can alter in real-time due to changes in their physico-chemical state influenced by external factors like temperature, humidity, solar radiation, dynamic loads over time, and resonance conditions. Various materials exhibit rheological phase changes, notably including anti-corrosive and film-forming paints in thick layers, bitumen, asphalt mixtures, specialized mortars, fixing and sealing putties for glazed surfaces, unique cements, and stabilized soils for road construction. It has been observed that during the use of construction works with composite materials undergoing rheological phase changes, the rheological behavior can shift from the Voigt-Kelvin (VOK) model to the Maxwell (MX) model and vice versa, especially in scenarios different from the designed conditions. These scenarios include the dynamic regime of structural vibrations and noise, solar radiation, dynamic effects from wind and intense precipitation, and the action of earthquakes. Understanding these factors is crucial for predicting the long-term performance and durability of composite materials in various environmental conditions. In this context, the study provides evidence from efforts to parametrically identify the resonance response of various materials with rheological phase changes under controlled vibrational conditions.
