¡ÈEverything breaks. Everything has a life span. So, there is no problem even if a thing breaks. But, it is a problem if a thing breaks all of a sudden.¡É

This is the stock argument of Kenichi Takahari, Principal of ¡ÈMonozukuri Shoka Sonjuku¡É. In designing a new product, it is necessary to first confirm the strength characteristics of the raw material. The easiness or facility of manufacturing needs to be considered as well, taking into account the function, performance and shape of the product suitable for its purpose. Then, you need to estimate how the force flows in the relevant shape (application), to which direction the force flows (connection methods with the adjacent material, restraining conditions, etc.) and when the force reaches its peak. It is not possible to manufacture an unbreakable product, but an engineer needs to control the ways of breakage of the product he designs. It is quite important to avoid a sudden breakage. For that purpose, it is necessary to predict the life span of the product by utilizing the knowledge of fatigue and destruction dynamics and to take various countermeasures. If the conditions, including the changes in the condition of the material with times, are known at the time when the product beaks, it becomes possible to have the product end its life peacefully. It is necessary to know how long the material can endure and how much allowance in strength is required. You need to pay your utmost attention in the designing of the product so that it accomplishes its life.
