Finite Element Method for Stress Analysis of an Infinite Plate with an Elliptical Hole Using Functionally Graded Materials

Nguyen, Dien
Abstract: This study investigates the stress concentration factor in an infinite steel plate with a thickness of 1 cm, containing an elliptical hole, subjected to biaxial loading at infinity. The elliptical hole has semi-axes a=5.0 cma… 0 cma = 5.0 \, \text{cm}a = 5.0 cm (major axis) and b=2.5 cmb = 2.5 \, \text{cm}b = 2.5 cm (minor axis). The applied stresses at infinity are a tensile stress of σ1=100 kg/cm2\sigma_1 = 100 \, \text{kg/cm}^2= 100 kg/parallel to the major axis and a compressive stress of σ2=−100 kg/cm2\sigma_2 = -100 \, \text{kg/cm}^2= -100 kg/ perpendicular to the major axis. The material properties include Young's modulus E=2.1×106 kg/cm2E = 2.1 \times 10^6 \, \text{kg/cm}^2E = 2,1.  kg/ and Poisson's ratioν=0.3\nu = 0.3  = 0.3. Using analytical solutions from classical elasticity theory, the maximum tangential stress at the edge of the ellipse is calculated as σmax=600 kg/cm2\sigma_{\text{max}} = 600 \, \text{kg/cm}^2= -600 kg/, yielding a stress concentration factor of kσ=σmax/σ=6k_\sigma = \sigma_{\text{max}} / \sigma = 6 =  =6. Additionally, a finite element (FE) analysis based on the Salerno and Sahoni problem for a quarter section of the plate results in kσ=3.1125k_\sigma = 3.1125 = 3.1125 for a configuration with s/r=5s/r = 5s/r = 5, showing a discrepancy of 1.3% compared to the theoretical value of kσ=3.1k_\sigma = 3.1= 3.1 from Peterson's Stress Concentration Factors. The results demonstrate good agreement between the calculated model and theoretical predictions, validating the accuracy of the FE approach for stress concentration analysis in such configurations.

Judicial Reasoning in Sidoarjo District Court Decision No. 199/Pid.Sus/2023: Corporate Criminal Liability in Environmental Crimes

Samsul Hadi, Dudik Djaja Sidarta, Renda Aranggraeni, M. Yustino Aribawa
Abstract: This study analyzes the judicial reasoning behind Putusan Pengadilan Negeri Sidoarjo No. 199/Pid.Sus/2023/PN Sda, a landmark decision involving corporate criminal liability for environmental violations in Indonesia. The… case centers on PT Surya Prima Semesta’s illegal disposal of hazardous waste (fly ash and bottom ash) without an environmental permit, resulting in the prosecution of its corporate director. Employing a normative juridical method, the research examines the court’s application of doctrines such as strict liability and identification theory within the framework of Law No. 32 of 2009 on Environmental Protection and Management. The findings show that the court adopted a formalistic, text-based legal reasoning model, treating permit violations as inherently punishable acts regardless of actual environmental harm. While the decision reinforces regulatory compliance and affirms corporate culpability, it lacks engagement with broader organizational responsibility and foundational environmental law principles like the precautionary principle and sustainability. This study argues for a more integrated doctrinal approach one that balances rule-based logic with value-oriented reasoning to enhance legal consistency, advance environmental justice, and align Indonesia’s corporate accountability framework with international standards.

The Function of the Deposit Insurance Corporation (LPS) as a Legal Protection Strategy for Customer Deposits Due to Bank Liquidation

Sri Anggraini Kusuma Dewi, Adam Pramana Putra
Abstract: This research aims to explore the role of the Deposit Insurance Corporation (LPS) in protecting customers when banks fail. The research methods used include policy analysis, case studies of failed banks, and reviews of related… elated laws. It is hoped that the research results will provide a deeper understanding of the effectiveness of the legal protection provided by LPS to customers in the context of bank failures and the related compensation claims process. The Deposit Insurance Corporation (LPS) has a crucial role in protecting customer deposits when banks experience liquidation. In this context, LPS functions as a legal protection strategy for customer deposits held in banks. This action is important to maintain public confidence in banking amidst economic uncertainty. In response to the 1998 monetary crisis, the Indonesian government issued a policy of guaranteeing bank payments, including public deposits, through LPS. The importance of LPS is revealed when banks experience failures that have the potential to threaten the security of customer funds. In this situation, LPS guarantees the customer's refund up to a certain limit, providing the necessary financial protection. This creates a sense of security for customers and promotes banking system stability. With LPS, customers can be assured that their funds are safe even if unexpected events occur in the banking world. The role of LPS as a deposit insurance institution is inherent in the government's efforts to regulate and supervise the financial sector. LPS plays a role as the front guard in protecting customer interests, maintaining financial system stability, and preventing potential losses that could arise due to the possibility of bank failure.
