Glass-ceramic materials are polycrystalline solids with a residual glassy matrix normally obtained by a controlled crystallization process of suitable glasses generally induced by nucleating additives [6,7].
Lately, glass-ceramic materials have demonstrated increasing potential of application in situations where better mechanical, chemical, and thermal performances are required [6,9].
The parent glass was prepared with appropriate amounts of the raw materials: Quartz-Minasolo; Al2O3-CT300 Almatis; Li2CO3-PA Dinâmica Química Contemp.; H3BO3-PA Ultra; ZrSiO4-Minasolo; MgO-Buschle & Lepper.
Oxides SiO2 Al2O3 MgO Li2O ZrO2 B2O3 Composition (wt %) 64.74 17.92 4.14 4.60 4.00 4.60 Raw materials were mixed in an aluminous porcelain mill containing alumina grinding media.

Among other causes, these stresses are due to the CTE (Coefficient of Thermal Expansion) mismatch of materials, high temperature and off equilibrium deposit.
This effect particularly occurs in semiconductor materials, making piezoresistive devices an attractive mean for stress sensoring in the microelectronic industry.
Materials were considered as isotropic and perfect adhesion of the model interfaces was assumed.

Burst Failure Analysis of a HFW Pipe for Nature Gas Pipeline Lixia Zhu1,2,a*, Gang Wu1,b, Jinheng Luo1,c and Zhenquan Bai1,d 1State Key Laboratory for Performance and Petroleum Tubular Goods and Equipment Materials, Xi′an 710077, China 2School of Materials Science and Engineering, Xi’an University of Technology, Xi’an 710048, China azhulx@cnpc.com.cn, bwuang010@cnpc.com.cn, cluojh@cnpc.com.cn, dbaizq@cnpc.com.cn Keywords: Pipeline Steel; Dent; Limit internal pressure; Plastic deformation; Burst Abstract.
The chemical composition of the pipe body material meets the requirements of GB/T 9711-2017.
The material properties of Φ 219.1 × 5.6 mm L415M welded pipe are as follows: Elastic Modulus was 206 GPA and Poisson's Ratio was 0.3.
(Internal pressure is 1.1MPa, the dnt depth is 10.41%) According to the net section failure criterion of materials, when the equivalent stress at any point in the wall thickness direction of the concerned area is equal to the flow stress, the pipeline reaches the limit state, and the flow stress can be determined according to the actual situation.
