Any loading can be understood as transient, but it can also be understood as a spectrum of waves. Treating dynamic problem inputs and outputs as a combination of waves (or wave spectrum) simplifies the problem by removing the concept of time. However, the solution is approximate and with certain limitations. You can use a response … Continue reading SolidWorks Simulation: How Do We Understand Response Spectrum Analysis?
SolidWorks Simulation: How Do We Understand Harmonic Response Analysis?
What is harmonic response analysis? Let's start this post by a simple example: A single degree of freedom oscillator loaded with a time varying force F. The solution to this problem is known in closed form. If the force F oscillates, the resulting displacement will oscillate in the same oscillatory fashion. The phase angle Φ, … Continue reading SolidWorks Simulation: How Do We Understand Harmonic Response Analysis?

Note: What is the difference between Nodal Stress and Element Stress?
Came across this neat explanation of the difference between nodal stress and element stress. I feel it is necessary to share this note because I have been asked several times about this question. This is definitely one of the fundamental concepts that a structural analyst should understand and be able to explain. Enjoy reading! It … Continue reading Note: What is the difference between Nodal Stress and Element Stress?
Analysis of the strength of rotor punching under centrifugal force
Rotor core punching Rotating machinery can withstand significant centrifugal force during operation. Therefore, the strength of a rotor punching should be analyzed. This problem was solved using Workbench. Considering the periodicity of the rotor punching and load, a 1/8 model was created and cyclic symmetric boundaries were defined. The model consists of a rotor punching … Continue reading Analysis of the strength of rotor punching under centrifugal force
Orthotropic Material-Modelling a Wood Pallet Using SolidWorks Simulation

Material nonlinearity: elasto-plastic analysis of a statically indeterminate truss
This is another simple problem of a statically indeterminate truss. Bilinear kinetic hardening material model is used. The beauty of this problem is that as the force increases, it can be expected that the vertical member and slant members will develop into the plastic stage consecutively. That will be seen later from the equilibrium path. … Continue reading Material nonlinearity: elasto-plastic analysis of a statically indeterminate truss
Nonlinear buckling analysis: considering both large deformation and material nonlinearity
In this post, we are going to do a nonlinear buckling analysis for a thin arch shell under uniformly distributed pressure. The configuration of the arch shell is as follows During the analysis, a linear buckling analysis will be conducted first to obtain the 1st-order eigenvalue (i.e. the linear buckling load) and eigenmode (i.e. buckling … Continue reading Nonlinear buckling analysis: considering both large deformation and material nonlinearity
Geometric nonlinearity: a simple two-member truss problem
In geometric linearity, the equilibrium equation is established in the undeformed state and will not be updated with deformation. In other words, we ignore the small deformation of the geometry to simplify the calculation. This does not seem to be in line with the core idea of structural mechanics, because the calculation of deformation is … Continue reading Geometric nonlinearity: a simple two-member truss problem
Plastic limit analysis of a statically indeterminate beam
A structure can become unstable when a load reaches its buckling value or when nonlinear material becomes unstable. It is possible to observe the full response of a structure under proportional (ramped) loads using elastic-plastic analysis in ANSYS, so the plastic limit load and the location of plastic hinges can be determined. In this post, … Continue reading Plastic limit analysis of a statically indeterminate beam
