Yield Criteria for Ductile Materials under Plane Stress01:25

Yield Criteria for Ductile Materials under Plane Stress

157
In designing structural elements and machine parts using ductile materials, it is crucial to ensure that these components withstand applied stresses without yielding. Yielding is initially determined through a tensile test, which evaluates the material's response to uniaxial stress. However, tensile stress is insufficient when components face biaxial or plane stress conditions This condition requires advanced criteria to predict failure.
The Maximum Shearing Stress Criterion, also known as...

Stress-Strain Diagram - Brittle Materials

2.2K
Brittle materials, including glass, cast iron, and stone, exhibit unique characteristics. They fracture without considerable change in their elongation rate, indicating that their breaking and ultimate strength are equivalent. Such materials also show lower strain levels at the point of rupture. The failure in brittle materials predominantly results from normal stresses, as evidenced by the rupture created along a surface perpendicular to the applied load. These materials do not display...

Shearing Strain01:20

Shearing Strain

239
The shearing strain represents a cubic element's angular change when subjected to shearing stress. This type of stress can transform a cube into an oblique parallelepiped without influencing normal strains. The cubic element experiences a significant transformation when exposed solely to shearing stress. Its shape alters from a perfect cube into a rhomboid, clearly demonstrating the effect of shearing strain. The degree of this strain is considered positive if it reduces the angle between...

Stress-Strain Diagram - Ductile Materials

653
The stress-strain relationship in ductile materials such as structural steel or aluminium is intricate and progresses through several stages. When a specimen is loaded, it initially exhibits a linear length increase, depicted by a steep straight line on the stress-strain diagram. It indicates the material is elastically deforming and will return to its original shape once unloaded. However, when a critical stress value is reached, plastic deformation begins. This stage sees substantial...

Mechanical Characteristics of Steel01:18

Mechanical Characteristics of Steel

410
The mechanical characteristics of steel are assessed through various tests that evaluate its strength, toughness, and flexibility. These tests include tension, torsion, impact, bending, and hardness assessments, each providing crucial information about steel's suitability for specific applications.
The tension test is fundamental for determining tensile strength. In this test, a steel specimen is stretched using a gripping device until it breaks. The data collected during this test are used...

Fatigue01:21

Fatigue

176
Fatigue occurs when materials rupture under repeated or fluctuating loads, even at stress levels far below their static breaking strength. It typically results in brittle failure, even for ductile materials. It is a critical consideration in designing machines and structural components subjected to repetitive or varying loads. The nature of these loadings can range from fluctuating loads like unbalanced pump impellers causing vibrations to repeatedly bending a thin steel rod wire back and forth...

Area of Science:

  • Geotechnical Engineering
  • Rock Mechanics
  • Materials Science

Background:

  • Underground geological engineering frequently encounters diverse rock types prone to shear fracturing.
  • Understanding rock shear behavior is crucial for preventing surrounding rock instability.

Purpose of the Study:

  • To analyze shear mechanical characteristics, acoustic emission (AE) behavior, and damage degree of various rocks.
  • To investigate the influence of joint angles and normal stress on rock fracture mechanisms.
  • To develop a constitutive model for describing rock shear behavior.

Main Methods:

  • Conducting shear mechanics tests on diverse rock samples under varying joint angles and normal stresses.
  • Monitoring acoustic emission signals to characterize rock damage and fracture processes.
  • Analyzing crack propagation angles and correlating them with applied stresses.

Main Results:

  • Rock shear behavior exhibits three distinct phases, with an elastic-to-plastic transition point.
  • Acoustic emission signals increase significantly in later stages of shear, varying by rock type (coal, sandstone, shale).
  • Crack propagation angle increases with normal stress, and joint angles/normal stresses effectively inhibit vertical fracture development.

Conclusions:

  • The study provides insights into rock bearing capacity and fracture mechanisms under shear loading.
  • A validated constitutive model accurately describes the shear fracture properties of different rock types.
  • The developed model and findings can enhance the stability of underground engineering surrounding rocks.
