Typical Model Studies

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Deformation occurs in axial and transverse directions when an axial load is applied to a slender bar. This deformation impacts the cubic element within the bar, transforming it into either a rectangular parallelepiped or a rhombus, contingent on its orientation. This transformation process induces shearing strain. Axial loading elicits both shearing and normal strains. Applying an axial load instigates equal normal and shearing stresses on elements oriented at a 45° angle to the load axis.

In analyzing a structural member composed of two different materials with identical cross-sectional areas, it is crucial to understand how their distinct elastic properties affect the member's response under load. The analysis involves assessing stress and strain distributions using the transformed section concept, which accounts for variations in material properties.
Hooke's Law determines stress in each material, stating that stress is proportional to strain but varies due to each material's...

Deformation of Member under Multiple Loadings

When a rod is made of different materials or has various cross-sections, it must be divided into parts that meet the necessary conditions for determining the deformation. These parts are each characterized by their internal force, cross-sectional area, length, and modulus of elasticity. These parameters are then used to compute the deformation of the entire rod.
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...

Impact Loading01:19

Impact Loading

914
Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.
In cases of elastic deformation,...

Temperature Dependent Deformation01:12

Temperature Dependent Deformation

677
In a nonhomogeneous rod made up of steel and brass, restrained at both ends and subjected to a temperature change, several steps are involved in calculating the stress and compressive load. Due to the problem's static indeterminacy, one end support is disconnected, allowing the rod to experience the temperature change freely. Next, an unknown force is applied at the free end, triggering deformations in the rod's steel and brass portions. These deformations are then calculated and added...

Area of Science:

  • Computational mechanics
  • Materials science
  • Finite element analysis

Background:

  • The Johnson-Cook (JC) dynamic failure model is widely used in simulations.
  • Local damage models can lead to mesh dependence, affecting simulation accuracy.
  • Understanding and quantifying mesh dependence is crucial for reliable simulations.

Purpose of the Study:

  • To investigate the extent of pathological mesh dependence in the JC dynamic failure model.
  • To compare the mesh dependence of the JC model with a continuum damage model.
  • To analyze the influence of different damage evolution mechanisms on mesh sensitivity.

Main Methods:

  • Orthogonal machining simulations were performed.
  • Two damage models were compared: JC dynamic failure and a continuum damage model.
  • 2D shear tests were conducted using various finite element (FE) mesh representations.
  • Realistic pearlite material properties were utilized.

Main Results:

  • Significant element size dependence was observed for the JC dynamic failure model.
  • Both the JC model and the continuum damage model exhibited similar degrees of mesh dependence.
  • Viscous regularization effects were found to be absent in the current study.
  • Damage evolution significantly impacts material response in both models.

Conclusions:

  • Mesh dependence is a significant issue in the JC dynamic failure model, stemming from local damage models.
  • The choice between the JC dynamic failure model and a continuum damage model does not substantially alter mesh dependence for pearlite.
  • Further research may be needed to develop mesh-independent damage models for dynamic failure simulations.
