Abstract
  The mechanical design of metals must deal with structures collapsing due to cracks occur in the material. This study focused on the edge crack at non-proportional cycle loading because it propagates quickly. This research attempted to determine two mathematical models that could predict the crack propagation ...  Read More

Abstract
  Leaf springs are commonly used in the suspension system of automobiles and are subjected to varying stress from dynamic loading leading to failure. An analytical method using formulation and solution technique classical laminated plate theory (CLPT) for design optimization of composite leaf springs under ...  Read More
