As we all know, finite element matrices are sparse and many memory can be saved if their sparsity is exploited. Due to the latter, we are often provoked to declare the nxn stiffness matrix as a sparse one just before the element loop. Be careful of this method since the larger the matrix the slower the assembly operations. There is a better and more efficient way to code the assembly procedure in Matlab. I will show how to accomplish this. For the sake of simplicity, the stiffness matrix of the two-dimensional heat conduction problem on the domain (0,1)x(0,1) is considered.

Having achieved many goals in my career of computational methods in structural mechanics, structure engineering, finite element method and computational simulation of structural construction process, I am interested in widening my professional horizons by seeking new challenges. I am looking for a postdoctoral position in computational mechanics and structural engineering.

hi all,

my name is christian, i'm a master degree student in mechanical engineering. i've been doing a swaging  process simulation using MSC.MARC, but i have a problem.when i ran the simulation, there were some node or element that penetrated into the other element and/or rigid body. i tried to change the value of contact tolerance and mesh, but i got the same result (pentrated still happened). what should i do to solve this problem?should i use mesh adaptivity? please help me ^^

These notes were prepared when I taught fracture mechanics in 2010, and were updated when I taught the course again in 2014.

Notes on other parts of the course are also online.
