Accurate predictions of thin sheet material springback during forming processes are great interest in the industry. However, sheets susceptible to buckling under shear loading. The present research aims at improving so-called Arcan setup for testing (1-5 mm) samples with large gauge areas (i.e., width about 21 by introducing anti-buckling devices mitigate sample buckling. Three monotonic and on...

Randomly oriented short fiber reinforced sheet molding compound composites (SMC-R) are among the most commonly used for automotive and many non-automotive structural applications. Many studies have reported static fatigue properties of SMC-R under uniaxial stress conditions. However, there applications in which they may be subjected to biaxial conditions their not been literature. The current s...

Although architectural smells are one of the most studied type technical debt, their impact on maintenance effort has not been thoroughly investigated. Studying this would help to understand how much debt interest is being paid due existence architecture and can be calculated. This work a first attempt address issue by investigating relation between source code changes. Specifically, we study w...

Structural health monitoring (SHM) is an emerging technology with great potential in structural diagnosis and prognosis. SHM systems can be passive or active. Active SHM systems rely on structural interrogation using active sensors (transducers) that can transmit and receive ultrasonic Lamb waves traveling at large distances in the structural material. Piezoelectric-wafer active sensors (PWAS) ...

Interface cracks are seldom subjected to pure Mode I or pure Mode II conditions. Station~y interface cracks between two distinct, bonded elastic-creep materials subjected to remotely applied mixed mode loading are simulated. The finite element method (FEM) is used to examine crack tip fields and candidate driving force parameters for crack growth. Plane strain conditions are assumed. In most ca...
