\n\t\t\t\t\t\t\t\t\tImagine um cen\u00e1rio em que uma amostra a granel \u00e9 aquecida uniformemente a uma taxa constante. Quando um material a granel aquece e se aproxima de seu ponto de fus\u00e3o, ele come\u00e7ar\u00e1 a perder sua rigidez. Se as indenta\u00e7\u00f5es peri\u00f3dicas (testes de dureza) forem realizadas com a mesma for\u00e7a alvo, a profundidade de cada indenta\u00e7\u00e3o deve aumentar constantemente, uma vez que a amostra est\u00e1 se tornando mais macia (ver figura 1). Isto continua at\u00e9 que a amostra comece a derreter. Neste ponto, ser\u00e1 observado um grande aumento na profundidade por travess\u00e3o. Usando este conceito, a mudan\u00e7a de fase em um material pode ser observada utilizando oscila\u00e7\u00f5es din\u00e2micas com uma amplitude de for\u00e7a fixa e medindo seu deslocamento, ou seja, An\u00e1lise Mec\u00e2nica Din\u00e2mica (DMA).\n\n \n\nLeia sobre a Transi\u00e7\u00e3o Precisa de Vidro Localizado!<\/strong><\/a>\n\n\"\"<\/a>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
