Announcement: Homework #3 on Chapters 5-6 Due Feb 7, Solutions for HW#1 Posted

This announcement serves to remind students that Homework #3 covering Chapters 5 and 6 is due on Thursday, February 7. Solutions for Homework #1 have been graded and returned, with the solutions now posted for review. It is important to note that the lecture slides for Chapter 6 are still incomplete. The advantages of using work functions in our analysis include precise derivation of forms, adaptability to different coordinate systems, reliance on variational principles in FEM, and ensuring the symmetry of the tangent stiffness matrix, which aids in stability assessments.

  1. ASEN 6107 Announcements HW # 3 on Chapters 5-6 TBP Jan 29, linked to Chapter 5 Index. Due Th Feb 7 HW#1 graded & returned today, solutions posted Slides for Ch 6 still incomplete.

  2. Advantages of Using Work Functions 1. Automatic & error-free derivation of residual and rate forms 2. Easy transformation to different coordinate systems 3. FEM derivations strongly rely on variational & energy forms 4. Tangent stiffness matrix guaranteed to be symmetric 5. Loss of stability can be assessed by static method (singular K)
