Abstract: The hydro-elasto-plastic theory independently created by Che-Min Cheng and his collaborators is a fundamental engineering science to investigate the mechanical properties of materials under violent dynamic loads. The theory has been in development for nearly 60 years since its establishment, and it has gone through the development stages of modeling, software, and engineering, and become increasingly mature. The series of engineering models developed form it have played a core supporting role in solving scientific computing problems such as strong explosive effects. However, in specific engineering applications, further development is required, and the following aspects should be done, such as improving the theory which can truly reflect the changeable behavior of rock mechanics, developing the mature model which can comprehensively describe the failure process of rock under violent dynamic loads, establishing a new computing framework which can meet the universal requirements of basic theory, conducting a variety of material tests which can provide all-round data requirements for numerical simulations, and establishing refined zones which can describe the damage characteristics of conventional penetration and explosion effects. To achieve the above, it is necessary to further improve the theory model, establish engineering frameworks and standards at the national level, and develop hydro-elasto-plastic model software packages and corresponding databases which can be plugged into the numerical simulation software system.
