Computer Science
Consider the following beam fix-supported at both ends. Its dynamic behavior is modeled
by the Euler-Bernoulli theory, the PDE of which is defined as
w
+ EI
- q(x, t) = 0,
where w is the deflection of the beam, p is the mass per unit length, E is the Young's
modulus, and I is the moment of inertia. The length of the beam is L.
Lo
Now, a car is traveling through the beam with a constant speed V. The live load of the
moving car is represented by q(x, t) in the PDE. q(x, t) takes a Gaussian profile, defined as
-2(x-Vt)2]
exp
L
2A
q(x,t)
where Lo is the length of the car (Lo ), A is the total weight of the car.
Overall Objective: A comprehensive application of what we discussed in the course to a
structural engineering problem.
• Part 1: Establish a general computer program by picking up a combination of explicit
time integration and finite difference to solve w. Briefly comment on the stability of
your method.
