There are some properties of the material that we can understand from the stress vs. strain diagram and load vs. deformation diagram like Elasticity, Plasticity, Toughness, Stiffness, Modulus of toughness, Resilience, Modulus of resilience, Proof resilience, Ductility, Mailability, Brittleness, etc. Elasticity When we applied force or load on solid objects, they will deform and change […]
📊Stress Strain Diagram📈(proportional limit, Elastic limit, Yield point, Ultimate point, Fracture point)
We surrounded by mostly two types of material (1) Ductile material (2) Brittle material Based on % elongation, Ductile and brittle material are categories % Elongation = (Final length – Initial length / Initial length ) * 100 % If % Elongation is less than 5 % then we can say the […]
Relations between elastic constants(Modulus of elasticity, Bulk modulus, Modulus of rigidity, Poisson’s ratio)
There is 4 elastic constant for isotropic materials. Modulus of elasticity (Young’s modulus) Bulk modulus Modulus of rigidity (Shear modulus) Poisson’s ratio In which 2 are independent elastic constants. This means if I have a value of any 2 elastic constants then You can find the value of all 4 elastic constants. Modulus […]
⚡Types Of Welding Position🔥
Types Of Welding Position In welding technology, there are some types of welding positions that have designation or coding according to the type of weld joint or weld connection. For bevel connections, it is indicated by 1G, 2G, 3G, and 4G, while for fillet connections, it is coded with positions […]
Tetrahedral Vs. Hexahedral Mesh (Mesh Comparison)
Tetrahedral Vs. Hexahedral Mesh (Mesh Comparison) As we know that the accuracy of CFD simulation highly depends on mesh quality. If mesh quality is not good but the solution procedure is carried out in the best way, then it may possible to achieve an inaccurate result. No one mesh type is universally acceptable. Accuracy of […]
Cell Zone & Boundary Conditions
Cell Zone Conditions & Boundary Conditions Cell zone and boundary conditions specify the thermal variables and flow variables on the boundaries of your physical model. Therefore, They are critical things of your ANSYS Fluent simulations and it is important that they are specified properly. Cell Zone Conditions There are mainly two cell zones available in ANSYS. […]
SPHERE OF INFLUENCE, TYPE OF MESH, BIAS AND BIAS FACTOR
SPHERE OF INFLUENCE, TYPE OF MESH, BIAS AND BIAS FACTOR The following local mesh controls are available: (1) Method Control (2) Sizing Control (3) Mapped Face Meshing Control (4) Contact Sizing Control (5) Match Control (6) Pinch Control (7) Refinement Control (8) Inflation Control (9) Gap Tool various option for local mesh controls in Ansys […]
Mesh Generation & CFD Steps
CFD Steps and Mesh Generation (1) First of all, you must create or choose a computational domain, and then a mesh generation (also called a grid); after that, the computational domain is divided into many small elements called cells (mesh). For 2-D domains, the cells are areas, while for 3-D domains the cells are volumes. You […]
ANSYS MESHING (CUTCELL) AND LOCAL MESH SIZING ON A BODY
ANSYS MESHING (CUTCELL) AND LOCAL MESH SIZING ON A BODY The Sizing group available in Ansys meshing allows you to control the following options: (1) Use Advanced Size Function (2) Relevance Center (3) Element Size (4) Initial Size Seed (5) Smoothing (6) Transition (7) Span Angle Center (8) Minimum Edge Length We already discuss 1st […]
Inflation Mesh And Transition Ratio
Inflation is an option to use when we need to refine the zone near to the wall. Inflation is use when analysis of boundary condition is done accurately by create finer mesh near to wall or near to boundary. Inflation is also useful for CFD boundary layer resolution, electromagnetic air gap resolution or resolving high […]
