Q) When a sound wave is traveling through a structure made of 2 materials (i and ii in 1D dimension), there is a reflection and transmission of the sound wave at the interface.
Does reflection or transmission affect the speed of sound within any of the media?. I understand that speed of sound...
Hello Eng-Tips team,
I am trying to solve the below problem analytically
∇∙σ + 𝑏_𝑥 = 𝜌 (𝜕^2 𝑢)/(𝜕𝑡^2 ) --> (1) is the governing equation
[Note: In the above problem, b_x = 0 (no body forces)]
IC: u(x,0) = v(x,0) = 0
BC: u(0,t) =0; u'(x=1,t) = F(t)/(A*E2)
[Note: Since force (F(t)) is applied...
I am performing a very basic FEM dynamic analysis. I am trying to find out how each node in the bar deforms in this analysis.
(1). For example, when I am using just 1 truss element:
Step1: Found the natural frequency (f) of the bar(using frequency analysis)
Step2: Found time period (T) = 1/f...
