Dynamic behavior of Sandwich Beam with Piezoelectric layers

Sandwich beams with composite faces sheets and foam core are widely used as lightweight components in many of the industries such as automotive, marine and aerospace applications due to its high bending stiffness and strength combined with low weight. Thus, it is important to gain knowledge of their flexural behavior under static as well as dynamic loads. Although extensive research has been devoted to the flexural behavior of composite laminates in general, the flexural behavior of sandwich structures is quite and obviously different. Several works treating the dynamic flexural behavior of sandwich beams have also confirmed the marked susceptibility of sandwich structures to damage caused by the low velocity impact of foreign objects. Impacts can damage the face sheets, the core material, and the core face interface. The type of damage usually found in the faces is similar to that observed after impacts on monolithic composites. However, the damage initiation thresholds and damage area depend on the properties of the core material and the relationship between the properties of the core and those of the face sheets.The modelling is done for sandwich beam with create volume option with dimensions known in the software

Mental health law in India

In India, the Mental Health Act 2017 was brought forth by replacing the Mental Health Act 1987, to remove the flaws that the previous version had. The new legislation allowed for decriminalisation of suicide in mentally ill patients, apart from clearly defining the term mental illness, and bringing in the Mental Health Authority. Despite the noteworthy provisions introduced in this legislation, it remains a point of criticism, which will be touched upon in this work. In addition to this, a brief overview of the manner in which the Australian jurisdiction deals with mental health, would also be covered
