Material Models Sources: Ludwik, Holomon, Swift, Wok, etc.

In summary, the conversation discusses the need for primary sources of all known empirical material models in order to analyze and understand the existing mathematical models of elastoplastic materials. The goal is to formulate an original mathematical model of the material. The conversation also mentions two articles that have been published on the topic and mentions the difficulty of finding publications from the beginning of the last century. The suggestion to contact a material science lab for assistance is also brought up.

TL;DR Summary
Need primary sources of all known empirical material models
Who can share the primary sources where material models are formulated: Ludwik, Holomon, Swift, Wok, Ludwikson, Hill and others?

That sounds like a pretty big research task. Can you show us what you have done so far? Also, is this for a schoolwork assignment? If not, why are you looking for this?

Maybe contact a material science lab and see what they can help you with. They might charge you though.

These documents are really needed for research work. The aim is to analyze the existing mathematical models of elastoplastic materials. This requires not only knowing the equations themselves, but also understanding their rationale. This is not for school assignment, this is for scientific research.
If there is an opportunity to see the primary sources, I would be very grateful. It is difficult to find publications from the beginning of the last century.
The result of all scientific work should be the formulation of the original mathematical model of the material. Currently, one article has been published that analyzes the well-known Ramberg-Osgood model: Belov P.A., Golovina, New York (2019). Generalization of the Ramberg - Osgood Model for Elastoplastic Materials: Journal of Materials Science and Performance. https://doi.org/10.1007/s11665-019-04422-3.
and one more article: Belov P.A., Golovina N.Yu. (2019). The deformation curve as an extremal of some functional: Science and business: Paths of development, 10 (100), p. 44-52.
Several articles are under publication.

1. What is the Ludwik material model?

The Ludwik material model, also known as the Ludwik-Holomon model, is a mathematical equation used to describe the behavior of materials under stress. It is commonly used for metals and alloys and takes into account both elastic and plastic deformation.

2. How does the Holomon material model differ from the Ludwik model?

The Holomon material model, also known as the power law model, is a simplified version of the Ludwik model. It only considers plastic deformation and does not take into account elastic behavior. This makes it more suitable for describing the behavior of materials at high temperatures or in creep conditions.

3. What is the Swift material model used for?

The Swift material model is a nonlinear viscoelastic model commonly used to describe the behavior of polymers and other viscoelastic materials. It takes into account both the elastic and viscous properties of the material and is useful for predicting the long-term behavior of these materials under varying stress and strain conditions.

4. How is the Wok material model different from other models?

The Wok material model, also known as the Wöhler model, is a fatigue life prediction model that considers the effects of stress amplitude, mean stress, and stress ratio on the fatigue life of a material. It is unique in that it takes into account the material's endurance limit, or the maximum stress that a material can withstand without failing under cyclic loading.

5. What are some common sources for material models?

Material models can be found in various sources, including research papers, textbooks, and online databases. Some common sources for material models include the National Institute of Standards and Technology (NIST) database, the American Society for Testing and Materials (ASTM) standards, and the International Organization for Standardization (ISO) standards.
