On Heat Transfer - Stress Analysis of Modified Brick (Reed Filler) Upon Its Production Stage

This paper aimed to scrutinize how burning process in modified brick's production impinge on crack as a result of stress differentiation between two consecutive layers of the brick's element. Diffusion engages in burning process of bricks, hence it generates thermal stress on element for different temperature between layers. This research focused on burning process in traditional production ward. Analytical of nonlinear equation and numerical solution, finite difference, were involved to obtain temperature value in each layer, followed by stress calculation. Based on the results, it can be concluded that crack occurs particularly on boundary area, since difussion tends to yield relatively more different value on it. Therefore, certain strategies, that may decrease this differentiation, are required to minimize number of cracks during brick's production.
