Hirsch model
The hierarchical model of seismology (HRSM) is a powerful tool for understanding earthquake processes, their associated hazards, and the impacts of seismic activity on human life and the environment. The HRSM combines a wide range of methodological approaches and scientific disciplines to support ......

tangent theory
Tangent Line Theory
Tangent line theory is the method used to understand the relationship between the origins of two sets of data in order to estimate the probability of a certain outcome. Through effective tangent line theory, data points can be compared to each other to identify the most likely......
Cournot model
Gunnarsson-Sheath model
The Gunnarsson-Sheath (GS) model is a phenomenological quantum many-body theory (QM) used to describe the emergence of collective properties in quantum dynamic systems. The model was developed by the Swedish physicist Ove Gunnarsson and his colleague Jürgen Sheath to desc......
Stainless steel 42% magnesium chloride stress corrosion test method GB 4334.8-84
Method of Stress Corrosion Testing for 42% Magnesium Chloride Stainless Steel
Stress corrosion testing is a method of determining the relative resistance of a material to corrosion damage under stress. This method is especially useful in evaluating the effects of various environmental conditions,......

GB 8163-87 Seamless Steel Pipes for Fluid Transportation
This Standard specifies the technical requirements, size, shape, weight, technical performances, and related requirements of seamless steel pipes (hereinafter referred to as pipes) for fluid transportation. This Standard belongs to state sp......
cold-formed steel
Cold bending steel
Cold bending steel is a valuable material used in many applications across multiple industries, from construction to automotive production. It is created by heating steel to temperatures above its critical temperature and then slowly cooling it. This process increases the machin......
delivery status
Delivering goods is an important part of any trade agreement. In order to ensure that the goods are delivered in a timely manner, parties to an agreement must organize the delivery of goods properly. This article will discuss the delivery status of goods under different conditions, the related law......
Metallographic diagram of ductile iron
Ball and Pebble Iron Gold Phase Diagram
The ball and pebble iron gold phase diagram is a graph that shows the interaction between the two materials. This graph allows engineers and scientists to predict the shapes and behaviors of materials when the two are joined together. Understanding this gra......
Fracture Analysis of 45 Steel Fatigue Specimen
Ductile-brittle Transition and Fracture Microstructure Analysis of 45 Steel Fatigue Specimens
Abstract
This paper mainly studies the fracture mechanism and ductile-brittle transition of 45 steel fatigue specimens from 980-1150 MPa stress levels. Modes of fracture, fracture surfaces, and fracture......
Al2O3-SiO2 phase diagram
Introduction
Alumina-silica phase diagrams are diagrams that illustrate the compositional relationship between alumina and silica, two important inorganic compounds found in nature and in numerous industrial products. The diagram is used by material scientists, chemists, and engineers to characte......
