The deformation regulations of aluminum alloy LC4 at high temperature were studied, and a precise constitutive model was developed.
And there is also simplified method using modulus of deformation by considering constitutive model of soil to calculate settlement.
The plastic constitutive model which involves DP yielding principle and relevant flowing principle was selected for high pressure conduction medium pyrophyllite.
Proposed a macroscopic constitutive model and relative equations which can be used to simulate theoretically measured stress-strain curves of loading -and unloading cycle.
Using the principle of virtual displacement and a rigid-plastic constitutive model, the stiffness matrix of the new contact element was deduced.
Based on the plastic flow theory of soils, an elastoplastic constitutive model for describing the stress-strain behavior of the saturated sands under the action of monotonic loading is developed.
The shale deformation of a given dam is the main issue of the study on underground openings and high slope, so it is important to discuss the viscoelastical constitutive model of the shale.
This paper focused on the simulation and explaining some mechanical characteristics of SRM with particle flow method, which will lay a foundation for the development of constitutive model of SRM.
Based on the inverse problem theory, it is explained that building the constitutive models of rock and soil is an inverse problem and four basic steps for modeling constitutive relations are proposed.
