The Philippines’ Bisaya dialect is a Malayo-Polynesian-based language belonging to the Austronesian family of languages. It is the language spoken in the provinces of Visayas and the communicative and trade language in almost all of Mindanao, all in the Philippines. With the Bisaya language’s popularity in the country and its widespread use, the de...
Conference Paper
An effective communication system is very important requirement for an efficient academic institution. Most academic institution in the Philippines relies only on a phone-based communication to establish contacts with and any of its continuants. Phone-based communication, however limit communications between offices and hence, contact can no longer...

Embossing and restoration technique is conducted as a simple method to strengthen sheet metals. Soft aluminum, mild steel and stainless steel sheets of different thickness are subjected to embossing and restoration at different sheet patterns and emboss height. Deflection tests are then conducted to evaluate the effects of the parameters considered...
Article
Full-text available
Embossing and restoration are utilized to improve the mechanical properties of sheet metal. By subjecting the sheet to these techniques, the section modulus of the sheet metal is increased. Moreover, strain hardening is locally introduced on the sheet. With these strengthening methods, sheet metal of thinner gage can be utilized with remarkable imp...

Embossing and restoration are utilized in strengthening sheet metals. The strengthening effect is due to the increase in the section modulus of the sheet as well as on the strain hardening that is locally introduced on the sheet metal. With these techniques, sheet metal of thinner gage can be utilized in sheet metal production with improved strengt...
Article
In this study, numerical simulations of flexural tests of sheet metals subjected to embossing and restoration process are carried out using LS-DYNA3D. Several models are created varying the number, position, and pitch of the emboss or restoration points. The emboss height and sheet thickness are also varied. Results show that improvement in rigidit...
Article
In this paper, numerical simulations of bending tests of aluminum sheet subjected to embossing in both sides are carried out using LS-DYNA3D finite element code. Finite elements simulations of the embossing process are first conducted at different emboss height and embossing direction. To verify the numerical results, embossing and flexural experim...
Article
Embossing and restoration technique is utilized as a simple method for strengthening sheet metal. Through this technique, sheet metal of thinner gage can be utilized with remarkable increase in mechanical properties such as strength and rigidity resulting to weight reduction of sheet product. In our previous studies, embossing and restoration techn...
